6br twist

[iukamedic]

Anyone shoot a 1 in 7.5 6mm Br. I’m about to pull the trigger on a build and can get a good deal on a 7.5 twist. Looking to shoot 105‘s or there about. The barrel is not chambered.

use berger twist rate stability calculator

you should be fine with a 7.5 twist

My Pac Nor 1:8 shoots 105's great out to 1K, no reason that the 7.5 shouldn't do the same.

I’ve had great luck with my 7.5T IBI in 6BR with 105s, 108ELDs, and will be trying 107SMKs soon. To be fair, a buddy has an 8T and see’s the same ragged one hole results with 108s.

1:7-1:7.5 is the sweet spot for 105 & 109 hybrids.

It'll be fine with a 1-7.5 twist.

I'm running a 1-7 twist on a 6BRA. Only reason I went 1-7 was so I could shoot the 110gr bullets.

I've shot plenty of 107smk thru it and it shoots just little holes with those as well.

I’m running a 27” 1:7.5tw kreiger at 4800ASL and it stabilizes the 115’s fine. I shoot 105 hybrids exclusively though as I ran out of 115’s and the speeds were better with the 105’s.
