Mike Stinnett Breaks ‘Unbreakable Record’ with .0077″ Group
.0077 World record benchrest groupOne of the most remarkable shooting records — and one that has stood for four decades — is the 0.009″ five-shot group credited to Mac McMillan. The NBRSA Light Varmint Record of .009″ for five shots (at 100 yards) was set on 9/23/1973, forty years ago. Experts have considered that record “untouchable”, “unassailable” — in other words “unbreakable.”
Well records are meant to be broken. It appears that Texan Mike Stinnett has broken the “unbreakable” .009″ NBRSA record. Mike shot a .0077″ five-shot group at 100 yards in a registered short-range benchrest match at Denton, Texas. This will be a new NBRSA record (and all-time world record) if approved. Mike was shooting a .30-caliber cartridge, listed as a 30 PPC, but there’s some talk that the cases were formed from a Lapua 6.5 Grendel case. No matter — this is a mind-blowing accomplishment, particularly considering that Stinnett was shooting a .30-caliber gun, which has considerably more recoil than a 22 PPC or 6 PPC.
Forum member Wes J. (aka “P1ZombieKiller”) reports: “My buddy Mike Stinnett was just confirmed as having beat the world record LV group at 100 yards in a registered match. His group measured .0077″ and he did it with his 30 caliber.”
Wes adds: “Mike shoots thousands of rounds a year… I have sat on the bench right next to him several times, and he has rattled off five shots down range in a matter of 2-3 seconds, and the groups have measured in the .1s. The guy can flat shoot. His wind reading abilities are mind-blowing. When he gets the right condition, he is fast. REALLY FAST.”

From a posting by Mike:
Several have asked so here is my equipment listing - no Pics as the targets have not been returned yet.
The hardware build actually started in 2008 with the goal of building two identical Benchrest rifles which could be used for both group and score. The idea was to shoot 6PPC and a 30 Cal without a base rifle change.
Hardware Description:
Action: Kelby Panda “Speedy Shorty” with Solid Bolt – PPC Bold Face. Kelby 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 setup on sizing dies for both rifles and ammo is interchangeable. Both actions were sent to “SPEEDY” to be blue printed along with new Jewell Triggers which were matched to the actions.
Stock: Larson (including action bedding).
Barrels: Krieger was selected for the barrels and after discussions with Randy Robinett (BIB Bullets) a 17 twist was identified as the correct safe solution. Ralph Stewart has cut all my chambers using a custom designed reamer. Again the concern was consistent headspace and Ralph has been able to keep my barrels within .0002 variance.
Scope: Leopold 45X Competition
Rings: Kelby Single Screw Tall.
Flags: Graham Wind Flags (large).
Tuner: Ralph Stewart
Front Rest: Farley
Bags: Micro Fiber
Brass: Lapua (Base case is 6.5 Grendel)
Bullets: Randy Robinett (BIB) 30 Cal. 114gr. 10 Ogive (my secondary – primary is 112 gr.)
Powder: H4198 – Weight?? (You can’t that that much in a 30PPC!) Velocity – 2980 FPS
Reamer: 30 STEWART (I just call it a 30PPC as that is what everyone expects, but it is in fact a custom design and Ralph deserves about 99% of the credit).
Dies: Sizing – Hornady Custom Shot / Seating - Ralph Stewart Custom
