Norma-USA Tac-22 Tops the Open Division at the 2016 NSSF Rimfire Challenge World Championship

Posted October 2016

The 2016 Rimfire Challenge World Championship was held in Woodville Alabama at the Carvern Cove Rimfire Range.  It’s a beautiful range that hosted 16 difficult stages, 8 pistol and 8 rifle. Each stage had 5-7 steel plate targets at distances between 10 to 30 yards.  The object of the game is to shoot the targets as fast as you can.  Misses added time penalties to the stage score. It is a race to see who can get the lowest accrued time.

This year, I was able to finish in 1st in the Open Division and 2nd overall out of 223 entries.  This is my third world championship title in the last 2 years. 17 year old phenom, Kolby Pavlock was the overall champion shooting in the Limited  division.


One of the most important parts of the game is having reliable ammunition.  After three world titles, Norma-USA’s Tac-22 has proven itself the leader in speed shooting competition.  There is no question that it is reliable and well suited to competition speed shooting.  It goes “bang” every time.  It shoots straight.  Norma demonstrates the value of excellent quality control.  As a subsonic load, it has noticeably reduced recoil allowing the quickest target acquisition following each shot.  For a speed shooter, it embodies everything you need to be the fastest. Tac-22 is the ammo I use and trust. Nothing else will do for this level of competition. 

I want to take a moment to thank the kind folks at Norma-USA. They have believed in me from the very start.  I am privileged enough to receive support from an ammunition company that is second to none.  With support from Norma-USA, I have been able to secure a place as the fastest Open Division rimfire shooter in the world.

Norma-USA Tac-22 Wins
Back to Back World Speed Shooting Titles

Posted August 2016


With Norma-USA's Tac-22, the sky is the limit!  At this year's World Speed Shooting Championships (also known as the Steel Challenge), I successfully defended my Rimfire Rifle Optics Division World Speed Shooting Championship title giving me back to back victories.

Norma-USA's Tac-22 is perfectly suited for speed shooting competitions like the Steel Challenge.  It is ultra reliable, low recoil, and very accurate.  To win at high level events like this, you rely on the ammunition to function flawlessly every time.  Norma-USA Tac-22 is exactly what you need to win.

The Steel Challenge is a test consisting of 8 stages that employ different shooting in a race against the clock with time penalties added for inaccuracy.  Some target arrays are right to left, left to right, near and far, big and small.  One stage requires movement from the shooter.  Each stage has 5 steel targets with the “stop” plate engaged last.  The time stops when you shoot the “stop” plate that ends the timer.  The total time with penalty for misses is your score. The winner is the competitor with the fastest time. There are 12 divisions, depending on the type of firearm used to compete. There are also “special” categories like lady, junior and senior.

I had a lot of fun at the Word Speed Shoot, and at the end of the day, that's what it is all about.  Fun.

In addition to winning the Rimfire Rifle Optics Division I finished 5th in Rimfire Pistol Optics and 9th in the Open Division shooting 9mm.  Most notably, I finished 3rd overall combined behind the legendary Max Michel and teenage phenomenon Kolby Pavlock.

Tac-22 takes 2nd Overall at the Old Fort Rimfire Challenge

Posted July 2016:

It seems everywhere I go, rain or shine, heat and humidity, or cold rain, Norma-USA's Tac-22 never fails me. This past May 28th and 29th I traveled to the 2016 Old Fort Rimfire Challenge also known as the Arkansas State Championships. Again, with Tac-22, I was able to win 2nd place overall out of 127 shooters. The tournament included 8 stages and 4 side matches. I used Tac-22 in both my pistol and my rifle, as I always do. The National Shooting Sports Foundation (NSSF) Rimfire Challenge consists of 5-7 steel plates, which you shoot as fast as you can. It is a 2-gun race with a rimfire pistol and rifle. When the buzzer sounds, it’s an all out race. Your cumulative time is your score; the lowest score wins. Brixey Nelson won the overall championship, defeating me for a second time this year. He is an amazingly fast shooter and an outstanding young gentleman. He is running very fast this year and is certainly on his way to a top finish at this year's World Championship in Alabama this coming October.


This year, a new competitive format was introduced as a ‘Side Match’. Contestants were placed in a single elimination bracket. Twenty-seven (27) shooters entered the event. The format is a head to head (H2H) event pitting two competitors against each other, the winner progressing to the next level until only one competitor is left. Each shooter placed the barrel of their gun on top of a sensor, which could detect if there was a false start. If a shooter's gun lifted off of the sensor before the green light, then a red light would flash, disqualifying the shooter for the false start. When the staging lights reached the green light, the race began. The last steel plate (Stop Plate) was propped against another sensor that would indicate which competitor finished first. Tac-22 performed flawlessly for me and enabled me to win the inaugural Head to Head (H2H) Gun Racing match. Tac-22's reliability and superior ignition propelled me through the opening round, quarter-finals, semi-finals and on to the finals. Each round, I faced a more skilled pro shooter. I was fortunate enough to prevail and win the side match and was presented with the cash prize.



Tac-22 Wins 3rd Overall at Lonestar Rimfire Challenge

Posted May 2016:


Norma-USA's precision manufacturing never lets me down. 

I just returned from Terrell, Texas after competing in the NSSF Lonestar Rimfire Challenge held April 30th, 2016.

Rimfire Challenge is a competitive event emphasizing speed and accuracy with both a .22 handgun and rifle hence, the designation “rimfire” in the name.   The challenge is to shoot an array of 5-7 steel plates as fast as you can. It also means your ammo must be reliable and work flawlessly in a pistol and a rifle.  Norma-USA's Tac-22 works beautifully for both of my guns.

The day before the match, a severe thunderstorm passed through the area, with a tornado watch in effect.  Luckily, the storm passed through and we were able to have a great match.

The best part of shooting Rimfire Challenge is the great group of people you get to meet.  It is family friendly; it is common to see entire families out shooting at the events.  Not many sports can have 3 generations of a family participating in the same sport.  Grandparents, parents and grandchildren can compete along side one another. There are divisions for the various age groups. My Dad, Chris Mitsuoka, was fortunate enough to win 2nd place in the Senior Division.  

My next match is May 28th-29th at the Old Fort Rimfire Challenge in Fort Smith, Arkansas.

3rd US Steel Nationals sm


Norma-USA's Tac-22 wins another one for me! The weather  was in the mid 70's and raining most of the time at the Smith & Wesson  U.S. Steel Nationals in Smyrna Beach Florida. Tac 22's outstanding reliability in these untoward conditions boosted me to podium. The competition was fierce and a failure to fire would drop a competitor 3 to 4 places in the results. The Tac-22's flawless functioning kept me in third place by a mere 0.15 seconds in the Open Rimfire Rifle Division.

I also managed to win the plate rack side match. The contest involved shooting a rimfire plate rack of 6 plates with a Tactical Solutions X-ring iron sight rifle. I won with a time of 1.32 seconds and was given the plate rack used in the side match as the prize. Since I flew in from California, I decided to donate the rack to a local Junior shooter that could cart it home with them. I chose Piper Hattox from Mississippi. She is a high level junior competitive shooter with a bright future ahead of her.

416 Rigby Norma Load



The 416 Rigby Norma load was the most consistent of the seven factory loads tested:  Tested in the Ruger 77 Magnum, this load launched the 450-grain Woodleigh bullet at 2170 fps (muzzle velocity), precisely as advertised.  Standard deviation for six shots was 7 fps.  Both 3-shot groups were similar in size. I am quite sure that this gun and load will shoot smaller groups than I can manage using the recoil-discomfort minimizing rest system I employed for this testing.  Most importantly, at 100 yards, this load shot only about 13Ž4-inches lower than the average for nineteentested handloads and six other tested factory loads, all loaded with 400- and 410-grain bullets.

Sweaty Buffalo


“ A great story of an exciting, ethical and a perfect ending of an African Buffalo hunt” As the winning entry in Nora’s Safari Club International “Win a Hunt” contest Ted will join Team Norma on a Red Stag and Driven Boar Hunt in Chec Republic!


Hunting Cape Buffalo in MozambiquetedBuffMoz2012

Today was the day that Bob from Rockford, MN and I were to go after our cape buffalo. Mr Zumbusch, the former Marine sergeant client had shot his buffalo 2 days previously and was a man of few words the evening after his hunt. While telling his brief story around the campfire that night, he did in fact look like a soldier who had just come back from combat. Over the years I have heard too many hunting stories of the hunter who climbed the mountain, almost met God and then climbed back down the mountain to tell about it. Something about Mr. Zumbusch made his story all the more credible. It was what he didn't tell me, that really got my curiosity going.

“ Teddy, tomorrow you are going to be one tired and happy hunter” was the last thing he said before he ate his dinner and went to bed on the day he shot his buffalo. Bob and I drove with our PH Julian to a spike camp that looked like some place where Teddy Roosevelt may have stayed at. It was more of a Boy Scout Camp on steroids. Safari tents alongside a river, with a thatched kitchen area and local staff to cook. They had parked a 8 wheel drive Argo next to a Swedish Hagglunds military vehicle with tank treads. Both vehicles were amphibious. Next to that was a 20 foot dug-out canoe that the locals had originally used to go into the wetter areas of the swamp. The area we were going into was approximately 16 square kilometers of papyrus and grass swamp. Dispersed amongst these wet areas, were 2 acre size islands of pristine pasture. This is prime habitat for a grazing ruminant as well as offering protection from poaching soldiers during a 17 year civil war.

Bob and I were up to get a start on the day. As I had just had dinner only 7 hours previously I was not that hungry, but we were told to eat as it might be a long day. That was an understatement. The outfitter told us that we needed to have a pair of Converse cotton high top shoes to hunt the swamps. They were the only shoe that would drain water, dry out while walking and not come off of our feet in the mud. We headed out into the swamp with three trackers in tow for a three hour drive into the swamp going about 20 mph. We eventually entered water and muck like I was used to duck hunting in in southern Minnesota. 3 feet of mud with 2 feet of water on top of it. Walking was not an option should we break down. Only 100 yards into the wet areas and the engine started to over-heat.

Julian told us that this had happened with the 2nd Hagglund the previous week. They had fixed the engine and it should not be happening. We were floating in muck and moving at 2 mph in a 1990s surplus Hagglund in the middle of Mozambique with an engine that I could see was far into the red-zone. It didn't help that the ambient air temperature was already in the 90Fs. All I could think about was if I had the telephone number to the Global Rescue insurance policy that I had purchased for this trip.

We were finally on a patch of dry hard ground and the vehicle was finished. Julian spoke Fanagalo with his trackers and told them that they had to decide amongst themselves who was going to have to walk/swim back the way we had come through the muck to get another vehicle. Alberto drew the short straw as the other tracker was only 5 ft. tall and could not manage the mud and water depth. The other tracker did not know how to operate a vehicle. This was the first time in four safaris that I had ever seen a tracker upset over what he had to do at his job. I didn't even want to think about walking through chest deep mud and water to get back.

We sat in the shade of the parked Hagglund vehicle when the real heat started to come on. It would be about five hours before Alfonso would be back with another vehicle. We drank water and moved every few minutes as our shade  isappeared. The humidity was also strong and all we could do was save energy. We were too hot to even talk and we had not started our hunt yet. Julian told us that we might go after Bob's Waterbuck in the swamp, but the buffalo would have to wait another day. By afternoon the heat and humidity would be unmanageable.

Eventually the sun was directly above us and there was no shade. We had brimmed hats and were thankful for all the water we had. We managed to get some sleep, but the heat kept waking us up. Anything to pass the time. I sat fumbling with my Norma Oryx cartridges for my .375 H&H, wondering is this was going to be the day.

We finally heard an engine and it was Craig the camp manager, pilot, PH and mechanic in the 2nd Hagglund with Alberto in tow driving an Argo. Craig told us that a pilot had seen a large heard of Buffalo about a mile away and they we  hould, “get on it.” Our spirits lifted and we were on our way. Soon after we saw a heard of about one thousand black buffalo in a sea of grass and papyrus. There were white Egrets in the air and they revealed the position of the heard. Bob was first in line and would do the first stalk. I stayed behind and watched from several hundred yards to the rear. You could smell and hear the buffalo in the distance. My heart beat went from slow to fast to slow more times than I could count. This is what I came here for. It would all be worth it soon.

After several blown stalks and the wrong wind, we let the heard run away and settle down a bit. Like previous buffalo hunts, I remembered that even buffalo get over heated and do not go far. The heard was grazing at a slow walk when we caught up to them. 5 ft. tall Francisco was carrying a small cooler with bottled water and we drank it every 30 minutes or so. I began to get dizzy as we ran through the grass while hunched over. Mr. Zumbusch lent me his leather gloves and I was never more grateful for a piece of hunting equipment ever. The ground was hard and the grass dry and sharp. We crawled 100 meters and waited for 20 minutes. The buffalo kept moving and we kept crawling. When we rested my dizziness passed and I was ready. My wrists got cramped from doing the dog-walk on all fours while shuffling my gun. I rested with Francisco while Bob made the final approach. I was feeling sick to my stomach and water did not help. I had a full stomach of H2O, but one can only absorb it at a certain rate. Walking upright would have been easy, but it was not an option. We were less that 200 yards and Julian wanted to get closer. It was all hand signals now and my vision began to blur. All I wanted was for Bob to get his buffalo. I would get mine another day. We still had 4 days left.

Alberto was dragging my gun and urging me in tracker-sign-language to move up towards Julian and Bob. There was a heard of 1,000 cape buffalo in front of us and I had only 50 yards to go to catch up with them. I felt my body absorbing water as my stomach was not so full anymore. My belt was soaking wet. Sweat had begun to permeate my cartridge belt holding the .375 Norma Oryxs. My head cleared and I saw that Julian had slowly put up the shooting sticks. He otioned for Bob to rest his rifle on the side of one of the sticks and shot from the siting position. They discussed which buffalo to take and finally a shot rang out. Julian turned to me and said in colonial British, “ Teed cum heea' quickly.”

I did the crab crawl with my gun on my lap and finally got where they were. Bob had a satisfied grin on his face while Julian looked me in the eye from six inches away. “Teed. Do not question anything I say, just shoot that buffalo directly in front of us. You have no time to look at the trophy. Just shoot it now man!”

I rested my rifle on my left index finger while steady on the stick and sitting. I found a crease on the shoulder of the beast and squeezed the trigger. 300 grains of Oryx bullet met its mark. He hunched like a rodeo bull and ran a few feet  before he collapsed. The heard moved off only a hundred yards as they were as tired and hot as we were. We finally stood up for the first time in over an hour. I felt the blood run back into my legs and the tension loosen from my shoulders. We drank some more water and the congratulations went all the way around. It had truly been a team effort in every way.

Bob ran to his buffalo and looked like an Olympic athlete who had just won Gold. While I on the other hand probably looked like an Olympic dis-qualifier. Julian slapped me on the back and said, “nice shot”. We later paced it out and it was just over 100 yards in distance. I was glad it was over.

Craig arrived shortly thereafter with the Hagglund while the trackers and PHs got to work with knives. We loaded up every part of those large buffalo into the vehicle, minus the hooves and rumen. Their build was much different than other buffalo I had hunted and I was curious as to their anatomy, so I examined it thoroughly. Not having any sanitary water available I dusted my soiled hands in the grass and we made our way back to camp. The Mozambican sun was setting. In Africa it takes only minutes for it to become dark. As we boarded our vehicle I could see our heard approaching our area again. They were anxious to start feeding in that same area. To my left and right I could see two other herds of equal size, less than a mile away. There were 3,000 buffalo that I could see from my vantage point. I took some photos in the fading light and was again in complete awe of Africa. Almost every day on this continent there is something that will
amaze you and that you will never forget.

As we motored back to the spike camp we drank water and then drank some more. My stomach started to remind me that it had been thirteen hours since we had had anything to eat. Craig had a container of cold meat pies in the vehicle and passed them around. My mouth was so dry that I could not get enough saliva to down the pie. The air began to cool to a comfortable 88F degrees and we felt a slight breeze in the vehicle. My neck was stiff as we drove the 2 hours back to spike camp to gather our things and then another 1 ½ hours to the main camp.

When we arrived, Mr. Zumbusch was sitting around the fire with the others enjoying a cigar with his rum and coke. I mixed myself another African Mind Cooler (orange Fanta and vodka) and drank half of it in one sip, just as he had done 3 days previously. He looked at me with an expression of someone who had been there before. His face said it all. “Well Teddy. How did it go?” he asked. “ I shot a 40+ inch Buffalo,” I replied. “ I an one tired but happy hunter today. ”

I’d like to thank Norma-USA for developing this ammunition and making it in quantities that have kept it available in the current marketplace. I believe that Norma Tac-22’s played a signifcant role in my competition successes and I will be using them exclusively for my future competitions.


I depend on Norma Tac-22. They have proven to be reliable, fast and accurate -Championship level competition ammo. World championships are won with good and lost with bad ammo. Tac-22 is a winner. Some people may be concerned with the higher price than bulk ammo, but what value can you put on failure proof function! After fying across country to compete, I would pay just about any amount for the guarantee my ammo would work every time. Norma's Tac-22 has outstanding ignition. It goes bang every time and that's more than half the battle.


For speed shooting competitions, accurate ammunition is critical. It doesn't matter how fast you can shoot if you can't hit anything. By using Norma Tac-22, I can count on my lead going exactly where I want. I never have any doubt about Tac-22's accuracy.


Tac-22 is fast out of my compensated rifle. It is subsonic and “light”, not like other brands that are “hot” and cause more recoil and slower splits (time between shots). With Tac-22, I can shoot fast. Together, we have won a world title at the 2015 USPSA World Speed Shooting Championships, also known as The Steel Challenge.
