Sunday GunDay: Whidden Smallbore Prone Championship Rifle

John Whidden is a 6-time National High Power Long Range Champion. He has also won major Palma matches in the USA and abroad. But John’s stellar marksmanship skills are not just limited to long range centerfire shooting. This month John added to his impressive list of shooting titles with a notable victory in the 2024 CMP Smallbore (.22 LR Rimfire) Championship match held at Camp Perry, Ohio.

In today’s Sunday GunDay story, John examines that CMP Championship match and the smallbore match rifle he used. This is a unique, one-of a kind rig, put together with a combination of premium components from multiple manufacturers. John’s ultra-accurate .22 LR rifle features a PQP 2500X action, Tec-Hro Fanatic stock, MullerWorks barrel, Uptagrafft Tuner/Bloop Tube, and Anschutz trigger. For different segments of the smallbore competition the rifle is fitted with iron sights or a Nightforce scope.

CMP Match Report — Whidden Wins Match with Final Shot
The 2024 National Smallbore Prone 6400 Aggregate Championship came down to millimeters. The event was part of the Civilian Marksmanship Program’s 2024 National Matches and was the culmination of four straight days of prone competition. Tight qualification matches saw the top three places separated by one point each, with John Whidden of Nashville, GA, leading the pack on the last leg of the match.

Whidden had been consistent throughout his entire National Matches appearance, having only dropped five points in the previous 15 rounds of the competition. His confidence continued as he took each shot. Then, unexpectedly, he pulled one left — just grazing the edge line of the 10-ring. An eye opener, to be sure.

Despite the close call, he pressed on. “A Prone 6400 Match is a marathon, and this, essentially, was a photo finish,” said Brad Donoho, CMP Smallbore Manager.

Whidden took his final shot, another 10. With a sigh of relief, John packed up his gear and walked off the firing line with a perfect score of 400 and the overall Open win in the Smallbore Prone 6400 Aggregate with a score of 6395-515X. “He finished out the match really strong”, Donoho said. “To see it all come down to the last shot was really incredible.”

Winning 2024 CMP Smallbore Prone Championship at Camp Perry

Report by John Whidden
The 2024 CMP Smallbore Prone National Championships are in the history books now. On the day before the match started, the CMP held a metric Dewar match. This was a bit of a warmup match and was well attended. The course of fire was 30 shots at 50 meters and 30 shots at 100 meters. I knew the match would be exciting as I got out of the car — the wind almost took the car door out of my hands! Yes, it was that kind of day.

Usually at the range, I can read the wind acceptably well, but there are occasionally some days when it just won’t come to me. The metric Dewar session was one of those days that I just couldn’t understand the wind indicators. I finished with a score of 575-24X which was below what I’d hoped for. I was feeling slapped around at this point!

Fortunately, the first day of the prone Championships was better. While still fairly windy, I found it much easier to read and finished up with 1599-103X leading the event. We shot iron sights for the first two days, and on day 2 Levi Clark shot the highest score and made up a point on my lead.

Days 3 and 4 are both shot with scopes on the gun. Usually with these scores, we see fewer points dropped. Shane Barnhart won day 3 with a blistering 1600-149X. Going into the last day I was only 1 point ahead and behind on X count. I knew with this tough group of shooters if I shot a 9 anywhere on day 4 I probably wouldn’t win it. I shot very carefully and tried to protect my points lead even if it meant giving up a few Xs along the way.

The day went well but I had a big scare on the next to the last shot. The wind picked up and I shot a 10.0 (these electronic targets will score in decimals) which is ALMOST a 9. I gathered myself for the last shot and felt my heart beating hard. I knew it had to be a good one because second place Nick Mowrer was breathing down my neck. Thankfully the shot stayed in the 10 Ring and I knew I had won the match.

Unique Rimfire Rifle with Premium Action, Stock, Barrel, & Tuner

The rifle I used for the match had just recently been built in our shop. Since opening the rimfire ammunition test range in May of 2024 we had the chance to observe some top-quality components in testing. After noting what was shooting really well, I decided to order a PQP 2500X action, a MullerWorks barrel, and a Uptagrafft Tuner/Bloop Tube. I had already purchased a Tec-Hro Fanatic aluminum stock suitable for the project and had an Anschutz trigger set aside.

MullerWorks has a highly respected standing for their barrels, especially in the rimfire community. I chose a MullerWorks 1:16″-twist barrel and finished it at 26″ OAL. I fitted a Tuner/Bloop Tube from Uptagrafft to the muzzle. This allows me to make the sight radius longer for iron sight matches and has a tuner integrated into the design.

The parts went together well. In the stock, I modified an action adapter that was intended to fit an Anschutz 54 into the Tec-Hro stock. I placed the action as far rearward in the stock as I could to make reaching the loading port easier. A benefit of the Anschutz trigger is that the trigger shoe is more forward than the Remington-type trigger, and this was a noticeable benefit in allowing the action to be mounted far back in the stock.

Call to Action-Maker about Fitting Anschutz Trigger
These PQP 2500X actions accept Remington pattern triggers but I use Anschutz triggers on all of my other prone guns. Because of familiarity I really wanted the Anschutz trigger on the new rifle. On the day before my action was to arrive I contacted Jerry Stiller who designed the action. I asked Jerry if the tang was long enough to retrofit an Anschutz trigger onto the action (Anschutz triggers are very large). He said he didn’t think it would fit. Well, things went well and the next evening I sent him a picture of my Anschutz trigger installed on the action. It has performed marvelously.

Once the rifle was all fitted and assembled, it was time to go to the test range. I shot through all of the ELEY and Lapua ammunition that we had available. One particular lot of ELEY Tenex and one lot of Lapua Center-X stood out as the winners. I shot several groups with each one and couldn’t determine a winner. Accuracy was excellent with group sizes averaging about 13.3mm (0.52″) outside to outside at 50 meters. The next evening I shot some more of each lot of ammunition and again neither ammo type was clearly better than the other. NOTE: 13.3 mm outside to outside is .303″ center to center.

Trying to break the ammunition tie, I decided to adjust the tuner on the third evening. I worked the tuner back and forth and arrived at the best setting. Up until now, I had shot the rifle with the tuner set as it arrived in the box, in this case setting number 500. On this particular rifle moving the tuner shrunk the group diameter by 4%. On some of my other rifles, I had seen a larger effect in the 14-15% range. I wasn’t unhappy though as the rifle was shooting well and importantly it was doing so very consistently.

When dry-fire training indoors, the rifle is fitted with a device on the end of the barrel that tracks barrel movement and shot location on a special electronic target. The device and target are sold together as the SCATT USB Dry-Fire Shooter Training System.

Secrets of a Rimfire Prone Champion — Whidden Wisdom
1. Shoot a High Volume of Ammo. There is really no substitute for rounds down range. The picture shows hundreds of spent cases — just a fraction of the several thousand rounds of ammo I shot from prone before the national events this summer.

2. Recognize the Difference between Training and Practicing. Training to me means that I have a defined goal that I’d like to achieve during that session. For example I may go shoot a match for training and my goal is to shoot all of my shots in the exact same wind condition and without making a sight adjustment for wind. This would help further my ability to recognize my desired wind condition.

3. Demand Top-level Accuracy from Your Rifle and Ammo. Often shooters are not objective enough about their testing and will excuse a bad shot with “I must have pulled that one” or similar comments. To win matches one needs reliable and durable accuracy across different temperatures and environmental conditions.

Major Benefits of Extensive Rimfire Ammunition Testing

Before the Championship at Camp Perry, I did significant rimfire ammunition testing, which proved very valuable. First I shot 10-round groups of all of the available lots. Next I shot 3 more 10-round groups of the lots that looked most promising. This is the same procedure we use for customer’s rifles when we test them. The worst of the initial 10 round groups was 25.4mm (1 inch) at 50 meters and the best was 12.4mm (0.49″) at 50 meters (measured outside edge to outside edge).

I want to illustrate the value of testing right here. Among the top ammunitions available one lot shot about half the diameter of a different lot. It’s just not possible to buy ammunition at random and expect the very best accuracy that way. The ammunition I chose averaged 13.3mm (0.52″) outside edge to edge at 50m across several groups. I decided to shoot the ELEY Tenex in the end. The performance of both ammunitions was equal but another of my rifles also shoots well with this lot of Tenex so that’s a bonus. Don’t think I didn’t also grab some of that Lapua Center-X and set it back for the right occasion!

Whidden Gunworks operates a state-of-the-art ammunition testing facility. You can visit the facility or ship your rifle to be tested with different lots of rimfire ammo. The Whidden facility features two testing lanes — one for testing ELEY ammo at 50 meters and a second for testing other brands (e.g. Lapua, SK, Norma, and RWS) at both 50 meters and 100 meters simultaneously, registering results for BOTH distances.
