Anyone use a 115 in the 6 BRA? Using 105's right now, and they are nice. Curious.
Thanks
Thanks
I’d start lower than that, maybe 27gr. That bullet has LOTS of bearing surface..Im using 31.1 h4895 w 105s getting 2926 fps in a 26in barrel. Thinking to start at 28.5 with 115. Thinking around 2800-2830.
I think that's gonna be about it for the 115 in a BRA. If you want more velocity, I would look into another cartridge.Finally tried dtacs in my bra, I could't get past 2825ish without getting alot of pressure at 29.6 gn of h4895.
Try some RL15. I have been working with it in my BRA and it'll go about 150fps faster (with 105/107) than Varget or H4895 w/o pressure signs in my gun.Finally tried dtacs in my bra, I could't get past 2825ish without getting alot of pressure at 29.6 gn of h4895. Didnt shoot well so Im thinking a different powder for the them would help
Look into MR2000 if you want speed, I ran this in a few different calibers with heavies that didn’t do to well with Varget. I was blown away by the lack of pressure and crazy speeds. It’s known to have temp swings but here it’s either 90* or 100* so didn’t matter much to me.Finally tried dtacs in my bra, I could't get past 2825ish without getting alot of pressure at 29.6 gn of h4895.

Thanks gilbert! I'm Unfamiliar with mr 2000, is it fairly stable? Summers here in norther NM can be 90-100 but early fall through spring can drop to freezing.Look into MR2000 if you want speed, I ran this in a few different calibers with heavies that didn’t do to well with Varget.

Have heard of alot of issues now with the current lot of dtacs. Anyone see this?
Not with the ones we were shooting this weekend at the Tubb ranch. I would not be surprised if his Tubb rifle was shooting under 1/4 MOA for the entire day.
A 1/4 min. isn't setting the world on fire, up close. Now a 1/4 min. at 1000 is...... jim
I guess that I did shoot 2" groups at 1000 with the old DTAC's is my point. Will the new one's?..... jimOh, give me a break.
