2022年1月1日 · Looking for a little advice on a 6mm BRA load development before I go ahead and start cranking out a match load. I built a 6 BRA on a LP Fuzion action with a 26" Rock Creek barrel. I'm currently using 107gr SMKs, Alpha Brass, 205M primers, and loading .020 off the lands. All shooting I've done so far has basically been done in 29-35 degree weather.

2020年4月7日 · Didn't see a specific post for the 6mm BRA and I am new to the cartridge. I will most likely run Lapua BR brass, CCI 450, H4895, and haven't decided on projectile.

2020年7月10日 · I run the BRA @2925 with 105s. Creed is kickass, until it is not (one barrel at 900, one at 1500) .243 went 1600. On my second BRA first one pulled at 2200, was shooting good, just did not want to lose it mid match. Fireforming is not an issue, shoot club matches with it, and it will not be the reason you miss.

2018年11月30日 · I'm ready to make the next jump and have decided on the 6mm BRA as it seems to be the better of many options. Brass is easier to obtain, longer barrel life, less powder, and a good magazine options. So, can anyone help with the reamer options and best machining options - ie freebore?? Plan on using a Bartein 1:7.5" twist medium palma blank.
