Story based on report by Sam Hall
Look at that target by Mike Wilson. This is one of the most remarkable displays of accuracy (and precision) in the history of long range shooting. This past weekend, Mike (aka “GA. Dawg” in our Forum) drilled a truly spectacular 1.068-inch, 5-shot group at 1000 yards, all centered up in the X-Ring. Yes, you read that right, a group barely over an inch at 1000, shot in competition at an official IBS benchrest match on July 21, 2018.
How small is that in angular measurement? Well 1 MOA at 1000 yards is 10.47 inches, so Mike’s 50-5X masterpiece is 0.102 MOA! Yes that will be pending IBS group size (and score) World Records. This best-ever 1K group* was shot at an IBS registered 1000-yard match at Hawks Ridge Gun Club in North Carolina. Other records have been shot at Hawks Ridge in the past, but this is the most jaw-dropping.
Sam Hall, past IBS National Champion and IBS 600-Yard Shooter of the Year, was stunned by Wilson’s accomplishment: “This is a truely awesome marksmanship feat — one of the best in history. I think I would trade all 14 of my 600-yard records for that one!”. Mike’s amazing target will be submitted for approval as new Group Size and Score IBS World Records. Official approval is pretty much a certainty. The previous 5-shot, 1000-yard IBS record is 1.397″ (50 score) by Tom Sarver in 2007. (The NBRSA 1000-Yard 5-shot LG record is 1.473″ by Bill Schrader in 2002.)
Posting on our Shooters’ Forum, Mike wrote: “Thanks everyone for the kind words. As humbling as this game is, when it comes together makes it all worthwhile! A very special THANK YOU to my traveling buddy, my son, Blake, and my wife Debra for allowing me to enjoy this crazy game.” Mike also wanted to thank his smiths and component suppliers.

World Record-Setting Cartridge and Load
Mike was shooting a 40-degree Improved version of the 6mmBR Norma cartridge. Long popular with Benchrest and 300M shooters, the 6mmBR was the original inspiration for this website. Yep, we started as www.6mmBR.com. The Improved version has extra capacity, allowing about 100 FPS more velocity when chambered with a long throat. For his record group, Mike shot Vapor Trail 103-grain bullets in Lapua brass. He loaded Hodgdon H4895 powder with CCI 450 (small rifle magnum) primers.
Praise from Fellow Competitors
Here are some reactions to Mike’s amazing group by our Forum members:
“Amazing target Mike Wilson! Your group might last forever as ‘the goal’ of 1000-yard Benchrest! Heck that’s a great target even at 600 yards.” — Mike J.
“Unbelievable!! Doing that under chosen prime conditions is an amazing feat but to do that in competition and to have everything to come together is just unbelievable. Amazing how far skill, precision, knowledge, and the products of this sport have come. Never thought we would see a group this small and well placed especially in the hills of North Carolina where the wind always blows. Congratulations. A true lifetime achievement.” — Yote Hunter
“I think that one will stand for a while. Hard work does pay off, but it don’t hurt to be one of the givers in the sport. Mike, you are ‘The Man’!” — Bill Shehane
“Awesome, awesome, awesome. Now the goal is to shoot UNDER an inch!” — Alex Wheeler

The 6mmBR Ackley Improved
Mike Wilson shot his spectacular group with a 40° Improved version of the 6mmBR cartridge with less body taper than a standard 6BR — the design is 0.463 at the body/shoulder junction (vs. 0.460 for standard 6BR). Mike calls his version of the 6BR Ackley a 6BRAW (“W” for Wilson). Sam Hall explained: “The 6BRAW is pretty much the same as a 6BRA or 6BR-AI (Ackley Improved). I sold the reamer to Mike last year. This has a 0.272 ‘No-Turn’ chamber with a 0.135 Freebore”.
This photo shows a 40° 6mmBR Ackley Improved (6BRA), as used by Tom Mousel in Deep Creek, Montana. Mike Wilson’s 6BRAW may be very slightly different. For Mousel’s 6BRA with 28″ Krieger barrel, the accuracy node is about 2980-2990 fps, so this gives up only 30-50 fps compared to typical Dasher velocities. Mike Wilson’s load runs about 2980 fps also.
In the past couple of years, the 6BR Ackley-type cartridges have been hugely successful in 600-yard and 1000-yard Benchrest. Sam Hall notes: “This year the little 6BR-AI has shot the smallest groups ever fired in 600-yard and 1000-yard competition. Back in April 2018, Bart Sauter, using a 6BRA, shot a 0.282″ 5-Shot group at 600 yards.” Bart’s stunning 0.04 MOA group is a pending 600-yard IBS World Record. (Read Sauter Story). Now Mike Wilson has a pending 1000-yard World Record with his 6BRAW.
Mike used an Italian Lenzi rear bag. Mike says the super-slick nylon on the ears of this high quality rear bag make for better tracking. The ears provide support but don’t “grab” the stock, reports Mike.
* There are two North American sanctioning bodies for 1000-Yard Benchrest, the IBS and the NBRSA. The previous 5-shot, 1000-yard IBS record is 1.397″ (50 score) by Tom Sarver in 2007. The existing NBRSA 1000-Yard 5-shot Light Gun record is 1.473″, shot by Bill Schrader in 2002.
