Twist rate on the 308 win

[Bobbyboy6br]

Does anybody know what the best twist rate for the 308 win using the Sierra 110 gr bullets .thanks

More info needed , type of bullet a regular lead core with jacket or mono . Flat base or boat tail ? What range are you shooting at and is it for a target/bench gun or hunting ?
Sorry I now see you have the bullet listed .
I say anything faster than 1/17 . A 1/10 to 1/13 is what most ( not all ) factories use .

I'm shooting 1 and 12 twist 22 inch barrel and 168 Sierra matching but wanted to know if the 110 gr bullets OK to shoot 1 in 12 t barrel

A 1:12 will shoot anything most people want to shoot. Until you start to get into the long target bullets. I From memory I think at the 175SMK you start to need an 11.25 or so and a 1:10 for the 185s and 200s.

You are fine.

I have a 1:12 5R X Cal barrel and it shoots 125 Noslers and 125 Sierra tipped matchkings really well with H4895. Never played with the 110's tho.

17-18 twist probably ...But that's not to say faster twists 12 or 10 even wouldn't shoot.
