Hello, This is my first post here. I actually tried to post this last night but it didn't seem to work. I bought some of the sierra 90 gr varminter for my 270 Win for a light weigh practice round but the accuracy has always been terrible. I just saw the 110gr VMax which have a BC of .370 whih is much closer to the 130gr Nosler B-tips that my gun loves. Does anyone have any experience with these bullets in the 270 Win? Secondly, I am considering having my Rem 700 rebarreled with a 24" barrel and was thinking about having it chambered for the 270 Ackley Improved. I can't find much info on the 270 AI, I did read that PO Ackley thought it was the least improved of all his cartridges. Is it worth it and how much improvement could I expect? Thanks for all the great info on this site!
