6BR twist rate

[PopCharlie]

My 1:8 shoots anything from 70 gr. To 105's well.

Mine too.....mine has .060 freebore as well.

My 1 - 8 Tw. 6BRX shoots 68 gr. - 107 gr. with no issues.

Is there some thoughts that for 105 type bullets and the 6br being a little slower than it’s variants, the 7.5 twist might work best…..

I have 7.5 twist barrel on my 6 Dasher and it shoots 105 hybrids really well.

I 26" Krieger .036" in standard 6mm BR Norma, I can shoot lighter that 80 grain with good results, but it will not outshoot my 23" 1-10 twist rifle. But anything over 85 grains, the 1-8 does better, it jucks with the 66 grain barts in the 1-8 twist, this is where my 1-10 shines to 80 grains, even the 95 grain Bibbs shoot good in the 1-10, but it wont shoot as good with them as the 1-8 barrel does.

I have decided never to use another barrel with this case slower than a 1-10,, and this is my proffered varmint twist, for 62- 80 grain bullets. But for anything 95 to 108 grain,, as heavy I use, the 1-8 is all I need!

I gave up years ago trying to make 1-14 6mm do anything unless it is in a 6PPC even a 1-12 twist will never be on one of my BR's again, unless it's a 22!!

The 75vmax shoots super accurate in my buddy's 8 twist 6br. Prairie dog killing combo.

I've had good luck with 8tw. And 75 gr or 80 gr. Bullets for accuracy.

I've got a 8 twist and it shoots great from 65 grainers to 107 grain bullets was surprised how well it shot the 65 but it shoots small with varget behind it.

I’ve got a wild hair to buy a prefit 6BR to play around with. PVA has a pretty good 4th of July sale, and I was about to pull the trigger, but they’re 6mm barrels all come with a standard 7 twist, I was planning on an 8. I’ll probably shoot 105’s most of the time, but would like the option to play around with the lighter 80-95 gr bullets. The Berger calculator says the lighter bullets would be stable, but does anyone have any experience with a 7 twist? My 2nd consideration is an 8T from preferred barrel blanks. This is just for fun/plinking, not competition.

Coming from the BR world I don't like to use any faster twist than is needed.
105's 8 twist
85-90 gr hunting bullets 10 twist
75-85 gr varmint bullets 12 twist
65 gr BR bullets 13.5 twist

That’s pretty much what I’m thinking also. Thanks

I mostly shoot the 105s. I tried a 1:7.5 twist last year and I'm back to the 1:8. Groups and scores told me loud and clear that was the right decision.
