Dang, I was going to say 1:8 twist and it's better to be safe than sorry, but I have never shot the 7mm 180's. Good luck either way.
 
Re: 7mm rem mag build

Yeah I just recently started reloading so I will be doing testing to get the right mixture that works best. I don't want to shoot anything less than 165 grain. I contacted Hart and they suggested I should do 1/8 because of the option to shoot heavier bullets with no problems.
 
Re: 7mm rem mag build

Select the bullet you wish to shoot. Go to the Mfg's website, the recommended twist is usually there.
If in doubt, twist a smidge faster than recommended. I use 9 on 180 and 189Gr 7MM's, but very high MV's.

I just bought the 1 in 8.5 in case the new 195berger comes out.
