I finally got my range membership and talked to a buddy about reloading some ammo. I have looked around online and see that it likes the 168 or 175gr bullets the best. My couple questions are 1. Have you had any experience with the 5r barrel, and if so, how did you like it? and 2. For longer ranges (500yrds for me) would the 175gr be better since it wont be pushed as much by windage, or will it not be that significant at that range? Thanks!
