[QUOTE="bobh918, post: 558832, member: 15833"] I went out on tuesday and fired a load that I was considering, but had mixed results today as something has drastically changed. The load was 91gr of Retumbo, 208 Amax, Fed 215 match, rem brass, seated .005 off the lands. Tuesday's results were an average velocity of 3105 that produced under a 1/2moa at 200yds. To say the least I was happy. Went today to test same load again with relatively same outside conditions, minus 10-15mph wind, the load chrono'd almost 125-150fps faster. Primers were flattened and slight plunger marks on the case. Kind of baffled now. I have read a few posts that people have lost faith in Retumbo. Is H1000 a little more forgiving? Should I try something else? I am in AZ and have a deer hunt in a few weeks and need a powder that is temp stable as the weather here is starting to change day to day. The rifle is a trued 700 sendero action, 30" braked Kreiger barrel, bedded MCM stock, extended mag box, leupold vx3 scope, etc. Also, the reloads were all full length sized bumping shoulders back .002, case sorted by weight, bullets sorted by weight, and loaded with same lot of Retumbo powder. Can someone share some thoughts or considerations on what I should do. Thanks in advance!! Bobby [/QUOTE]
