Today's Daily Bulletin features bullet-maker Bart Sauter and the wicked accurate 6 BRA rifle with which he won the 2021 Tack Driver II match. This is an interdisciplinary match for score AND group at 300 meters.
Sunday GunDay: Bart Sauter’s Tack Driver Match-Winning 6 BRA « Daily Bulletin
The Tack Driver II Showdown The Tack Driver Showdown is a 300 meter, one-of-a-kind match designed to determine the most accurate rifles in the world regardless of discipline or class.
I strongly recommend that all competitive BR shooters read the article. There is a fascinating discussion of the tests Bart did to determine to shoot his 6 BRA rather than a 6 PPC. Basically the 6 BRA had about HALF the wind drift at 200 yards! That was shooting 103gr 6mm bullets vs. 68-grainers in the 6 PPC.
OK, cut to the chase. EVERY bench shooter on this Forum should watch this video by Bart. This is full of really good advice about bench set-up and gun handling. I do not exaggerate -- this is one of the most informative bench-shooting videos I've seen in the 18-year history of running this site. Thanks to Bart for making this video, at my request, just for this article.
WATCH IT -- you'll be glad you did! At the very end of the video, Bart explains and demonstrates how to shoot fast but steady. He sends five rounds downrange in 9 seconds. Remember this guy holds the IBS 600-yard world records for both LG Score Agg (199) and HG group size (0.311")! SEE IBS Records
Cartridges Left to Right: 6 PPC, 30 BR, 6mmBR, 6 BRA, 6 DASHER. Those five cartridges represent 85% of cartridge types used at the Tack Driver II match.
The Drift Test -- 6 PPC had TWICE the lateral drift at 200 yards at 6 BRA:
The real eye-opener came when Jim and I conducted a drift test at 200 yards comparing the 6 PPC with 68gr Boattail Avengers to my 6 BRA with 103gr Bart’s Hammers. For the test both rifles were tuned as well as possible. The idea was for both shooters to hold the same point of aim for each shot (total of 5 per sequence). The shots were fired simultaneously by conducting a count down for example “One, Two, Three, FIRE!” Winds were 7 to 10 mph.

Each shot was intentionally fired in a different wind condition over flags. The first 3 shots from the 6 BRA formed a nice 0.300″ group while the 6PPC spread out to a 0.650″. The final two shots were fired in a hard crosswind pushing to the right then a hard crosswind to the left. The 6 PPC was push to over a 1.6 inch group while the 6 BRA kept them to around an 0.850″. The test was so conclusive that during the drive to the match Jim abandoned his 6 PPC, and we doubled up on my 6 BRA.
