Guys,

I'm trying to find a cut rifled 7mm barrel in 1-8.5, 1-8.7 twist with no luck.

My question is, can I stabilize the 162 amax with a 1-9 twist? Am I giving up anything with the 1-9?

Build will either be 7mag or 280 AI used for deer and target up to 700 yards.

thanks

Re: 7mm twist

1-9 will be fine for anything in the 162-168 range. Chances are, you'd only see benefit for anything faster if you step into the 180-200gr projos.

I run an 8.7 for the 180's and 200's but how much difference that 0.3 twist rate difference makes I couldn't tell you.

I run a 1/8.7 twist. Hold off for it if you will be shooting 180's and the new berger hybrids.
