[QUOTE="el matador, post: 1303387, member: 12193"] The gun I mentioned above is fairly accurate, and has shot a few sub-0.4 MOA groups with 208 grain Hornadys. The test target had a 1/4" group, and I have not been able to shoot a single group that size. I called Cooper and got the load data from them, and have gone through several rounds of load development with identical components and seating depth. Tried cleaning, torquing screws, etc. I've tried the whole gamut of different seating depths as well. My best group with those loads was 1/2", but that was a one-time deal. I haven't found a load that will shoot consistently under 3/4 moa and I've shot around 50 groups. I have other rifles that shoot routinely in the .2s and .3s so I'm fairly certain the problem is not with me. Here is a thread about the chamber problems: [U][U][U][U][URL]http://www.longrangehunting.com/forums/f37/expert-opinions-wanted-chamber-problem-184708/[/URL][/U][/U][/U][/U] [/QUOTE]
