Re: pro and con of 308 cal twist of barrel?

I personaly run a 1-10 on all my 30 cal rifles unless i'm shooting realy realy long bullets or heavy sub sonic then I may go to 1-9

I have run 110 V-amx bullet out of a 30-06 Ackley as hard as the Lapua brass would stand with great accuracy , in the 1/2moa range , the same rifle would shoot 168 Bergers into 1/3moa consistantly all the way to 220 gr SMK's into 1/2moa so I don't think that you can "over spin" a bullet unless your getting to the point of them comming appart.

I'd rather have a little more spin than not enough , I've seen a realy expensive suppressor destroyed by shooting a sub sonic 220gr SMK for a 1-11.25" barrel

Re: pro and con of 308 cal twist of barrel?

it seem that 1/10 is the winner over most conditions ....now with a 16'' barrel with 1/10 for 700 yds would 168 grain work and what powder for the best burn etc thxs to all...
