Thread: Help needed for 308 subsonic load

If you are going to stick with the 220gr start at about 12ish grain trailboss and work down until they go subsonic.

Its 1:8 twist too fast for 151gr cast? Making the bullet fly apart?the reason why I choose 220gr is purely based on the fast twist. Would not 1:10 1:12 much suitable for 151gr?
