[QUOTE="Jesse09, post: 1108543, member: 88547"] I didn't hear from anyone, but decided to test a different procedure this morning: I shot one 3-shot group at a time, cooling the barrel in my rifle cooler for five minutes between shots. This eliminated the extended rise in temperature that results from round robin shooting. This was my second time out with the new rifle, and I've finished load development. I settled on a muzzle velocity of 3490 fps, which is fast enough to require an adjustment of only one MOA, plus or minus, out to more than 300 yards. After cleaning and fouling, I shot three test groups of three shots each: .176" .850" .323" I think I can be more consistent after the barrel is broken in and after all the new brass is fire-formed. If anyone wants a referral to an excellent custom rifle maker who delivers on time, let me know. [/QUOTE]
