6BR vs. Dasher vs. 6BRX for 600 Yards
After scanning the equipment list for the recent 600-yard IBS Nationals, one of our readers noted how the 6mm Dasher dominated the Top 10 list in both Light Gun and Heavy Gun Classes. But Sam Hall won the Grand Agg with a straight 6BR, Mike Davis won the Heavy Gun Agg with a 6BRX, and Richard Schatz won the Light Gun Agg with a 6mm Dasher. So which cartridge should you pick? What’s the best for the 600-yard game — 6BR or Dasher or BRX?
Sam Hall, 2008 IBS 600-yard Shooter of the Year and back-to-back 2009/2008 IBS 600-yard National Champion, offers this advice:
“I shot a Dasher most of this year at IBS 600-yard matches and shot a no-turn BRX in a couple of shoots. I even tried a BRDX (40° improved with a longer neck than Dasher) in a practice barrel. By looking at the results on my target, I would never have been able to tell the difference between any of them if I did not already know what cartridge I was shooting. The 6BR or an improved version are just downright inherently accurate. They are all easy to load for and tune. I do believe the 6-6.5×47 Lapua is harder to get tuned than the 6BR. There are always the exceptions though. I have been beaten a few times this year by one exceptionally good shooting 6-6.5×47.
My next step is to try a no-neck-turn 6BR. I have been beaten by some a few times. I am now wondering if neck-turning is worth the time. A lot of the top BRX and Dasher shooters are not turning their necks and doing extremely well.
In my opinion pick your favoite BR or improved version, learn it well, practice, and don’t deviate. If someone you know shoots a BRX (or Dasher) and has a lot of experience with it — that is a good head start for loads. You can then compare what shoots good and what does not. I sure did not learn everthing on my own. I got some good load info here on this website (AccurateShooter.com) and I used to hound Terry Brady to death for loads to find out what he was winning with. Don’t be afraid to ask questions! I still do! Good luck and have fun.”
