When is a 14 twist used in a 6BR?? I have been reading on here that if you want to shoot anything over say 70 gr. you need a faster twist. Then I read that an 8 twist will fire anything well so why not a 9.5 or a 10 twist ?? I have a Savage 243 take off barrel that is 9.5 and a smith told me it wount work, I need a 14 twist. I will not shot over 200 yds. but might want to shoot some 90 plus stuff. Thanks for ant help you can give me.
Why a 14 twist in 6BR
- Thread starter David Clark

A 14 twist is for light bullets. The slower the twist the heavier the bullets you can shoot. If your shooting comps at 600 yards or more, you might want a 8 twist to shoot 105 grs or higher. If your wanting to shoot 90ish grainers i would go with 9 or 10 twist. But if you get an 8 twist you can shoot pritty much whatever you want. Or should i say whatever your barrel likes. (for lighter bullets)
Josh i think you ment the faster tw. shoots heavier bullets...

David.. i think your smitty meant that the 14tw won't work w/ 90gr an up
i have a 14tw an 75gr bullets seems to be a limit for tight groups past 300yrds [68gr. being better]..
i'm new to 6Br an have not really tested a lot of bullet weights but i can see pushing a heavey bullet " if thats what you want " needs a faster tw.
why spend $ on a used barrel to rechamber buy a new one with the tw you want.. in the long run it will work out better an be more postive... just my .02$

I have a 13 twist i shoot 68gr and 80gr Berger's very well. i can't get the 105 and 107 to shoot that well.
I can't give you exact data for H322 in a 1/13 or 1/14 twist using 68 grain bullets, but I can tell you that when I tried it in my guns it was not a good powder choice for them and I abandoned it after a dozen or so test firings.. I did and am doing a world better using N-135.
Tests were shot using precision ballistics 68 grain BT bullets, Fed 205M primers in a shilen select match 1/13 barrel at 200 yards, 5 shot groups, 2 groups for each powder charge on 2 different days. Same procedure for a 1/14 shilen select match.

You'll be shooting to 200yds, there's no reason to even mess with 90gr bullets. A 14" twist will be perfect and shoot bullets to about 70gr with great accuracy. The 6BR will be fast and unGodly accurate with 55-65gr bullets through a 14" twist. It takes much longer range than 200yds before there's any advantage to a 90gr bullet. The 6BR shooting lighter bullets much faster has a much flatter trajectory and less wind drift out to way past 200yds. It takes awhile before the heavier bullet starts to show any advantage.
The 6BR is such a good cartridge, I wouldn't waste time rechambering a Savage barrel. Get a good custom barrel and the gun will be a pleasure to use. It'll be more accurate than anything you've had and clean up very easily.

Dave, I have 2 6BR's. One a 14 twist, and the other a 8 twist. I use the 14 twist mainly for varmint hunting out to 300 yards. It is devastating on whistle pigs here in Pennsylvania. It will shoot up to the 70 grain bullets, but the 55 Sierra blitze makes red mist out of them. It will group well less than 1/2 inch at 100 yards. If your shooting no more than I would say 400 yards, then all you really need is a 1-14 twist. You just have to stay with lighter bullets up to 70 grains. But that is plenty...
I have a 14 twist and shoot the 70 Nosler BT using H322. I have made many hits on prairie dogs out to 600 yards with that rifle. I'm having a new one built with an 8 twist so I can get out to 1000 yards.
In my 14 twist I have found that just about any bullet from 55 - 70 will shoot pretty good with 30 grains of H322.
