[QUOTE="Freebore, post: 263218, member: 873"] So got back this week from Fla. (it was nice fish were biting) and ran 47.5 of 760 under a 145 Speer Sptzr. CCI-250. The group measured .482... because I could not believe what I was seeing in the scope and pulled the last one or would have been tighter. Velocity was 2830 avg. just what I had been expecting and NO extraction/ejection issues. This was using nickel brass. The factory barrel load was 49.0 of 760. Same primer just different brass...nickel plated. So the rifle is doing what I wanted and expected after the re-barrel/finishing job. >2800 fps and under .500 groups. I just have to use nickel brass. Don't you just love a custom sometimes.!! treeman, read back a few post and you will see we took chamber from 320 to 280 finish. [/QUOTE]
