Smallest 5-Shot, 100-Yard Group in History — Be Amazed

All target shooters strive for perfect shot placement. Well one man has come closer to perfection than any other shooter who ever lived. You are looking at Michael Stinnett’s .0077″ NBRSA world-record group, the smallest 100-yard 5-shot group ever shot in the history of rifle competition. The group was certified at .0077″ (though labeled .008″ on the range-signed target below). A moving backer verified that this was FIVE shots — no question about that. You may be surprised but this was NOT shot by a 6 PPC, but rather a .30-caliber wildcat, based on the 6.5 Grendel.

Call it stunning, call it humbling, call it amazing. It is, quite simply the apotheosis (“perfect example”) of accuracy. This is what we all hope to achieve. It’s staggering to see that a rifle can drill FIVE perfectly-overlapped holes — the last virtually indistinguishable from the first — at a target a football field (100 yards) away. It’s great to see a benchmark like this, if only to remind us what is possible in our sport of precision shooting. (Sighters appear below record target.)

Mike’s amazing group stands as a NBRSA Light Varmint Class record. But it is also smaller than the current 5-shot, 100-yard records for all other classes, even Unlimited (Rail Gun). Likewise Stinnett’s .0077″ group is smaller than the IBS records for all classes:

Below is a larger-than-life-size view. Using this photo we measured the group with target-calculating software, and it came out .006″ (the software only goes to three digits). We recognize that it would be much better to work from the real target rather than a photo, so we are not challenging the official measurement in the least. But this does confirm that this is a phenomenally small five-shot group.

The Record-Setting Rifle and Cartridge
Many folks have asked about the gun and ammo that produced the .0077″ group. The Light Varmint-class Benchrest rifle was chambered as a .30-caliber wildcat, the 30 Stewart, which is based on the 6.5 Grendel case necked up. Mike was using Hodgdon H4198 powder behind BIB 114gr, 10-ogive bullets. Notably, the record-setting ammo was pre-loaded before the match. Here is Mike’s tuner-equipped rifle.

Record Rifle Equipment Report by Mike Stinnett
Action: Kelbly Panda “Speedy Shorty” with solid bolt and PPC-diameter bolt face. Kelbly was asked to build several actions which were identical with the intent to eliminate any variance in head space between the two new rifles. This helped me use a single set-up on sizing dies for both rifles and ammo is interchangeable. Both actions were sent to Thomas ‘Speedy’ Gonzalez to be blue-printed and have Jewell triggers installed.

Reamer: 30 STEWART (I just call it a 30 PPC as that is what everyone expects, but it is in fact a custom design and Ralph deserves about 99% of the credit).

Barrels: Krieger was selected for the barrels. After discussions with Randy Robinett of BIB Bullets, a 1:17″ twist was identified as the correct, safe solution. Ralph Stewart has cut all my chambers using a custom-designed reamer. [Our goal] was consistent headspace and Ralph has been able to keep my barrels within .0002 variance. The barrel tuner also comes from Ralph Stewart.
