All, I am about to have a LR rig built by Proof Research. I am wondering what the best twist rate for the following set up would be? 300 win mag 26in Match Grade barrel: shooting the 185 grain Hunting VLD bullet by berger sometimes shooting the 168 grain Hunting VLD bullet by berger Also, If I wanted to use the 210's on browns and grizzlies would the above recommended twist rates harm a shot that would be under 200 yards. I have contacted Berger via email with no response yet. So I am wondering what the communities thoughts are on the question. Thank you in advance for your feed back.
