6BRA for 300m Comp. – F Class Style

[6brbb]

Am after some recommendations for a new rifle in 6BRA for 300m competition. We shoot a little of it here in New Zealand in local and national competitions; we have a FClass division which is a lot of fun, and you can learn a lot from shooting 60 scoring shots in the wind over a 1 hr period (usually less!); is like 6 10shot FClass matches in a row! I have most of what I need to start with; reamer(#1323), Alpha brass on order, and a supply of H4895 (ADI2206H) & Varget (ADI2208).

I will likely go with a 1.25 inch bull barrel and have it finished at 28 or 30 inches. Am keen to get a recommendation of what would be a good bullet and twist combination.

Thanks for your help.

if you can get them barts hammer 105gr

Any 105 bullets and a 1-8 twist.

so0rry but with that many shots in a short time there is no need for a bra nor 100 anything.
go with a straight 6mmbr and bullets in the 75 to 90 gr range.
less powder lighter bullet less heat, consistent longer

These flatbase bullets go lovely in the std 6BR at 300. Sort of like a bridge between a 6PPC/68gn/100yd and 6BR/105/600yd combination

My thoughts exactly. Std 6BR with either 87-88 or 95gn bullets

Light bullets in a 6 BRA are far too limiting. With the 105 weight range and a 1-8 twist you can compete from 100 to 1000 yards. I've shot mine at 1000 and it did as well as the 300 WSM I was shooting at the time.

At 300 yards the BRA with a 12 twist shooting the good 80 gr bullets at 3375 fps with 8208 is a pretty dang good load.

8 twist, 29.8 of h4895, cci 450, berger 108 with a .003 jam works for me.

While not F-Class, I shoot a 310-ish yard score match pretty regularly. It's discrete shots at different targets, not running them in a condition. Sure, you can do it with a straight 6BR, but I don't think it's inherently more accurate than a BRA and you'll definitely leave some velocity potential on the table. So why? The guys that win with 6mms are shooting either 6BR, 6BRA, or Dashers with 7.5-8twist barrels and 105 class bullets. The other favorite is the 6.5x47. It's tough to win with a PPC, a slow twist 6BR variant, or a 30BR even if they're potentially more accurate in ideal conditions.

I think Bart Sauter won the Tack Driver with a BRA and a 105 class pill. I suspect if he thought there was a better tool for the job, he'd use it.

30.3 grains of H4895 and just about any bullet from 103-108 will be an extremely good starting point! I personally love the Berger LRBT 108's over anything I have shot from this little cartridge. 28 or 30" I have had fantastic results from both. I'm in Texas so super hot high hummidity so I opted my last barrel to a 30" to see if I could run a little less powder but it still ended up at 30.3. the lots will vary, but something in that range will do you very well.
