[QUOTE="jdmecomber, post: 1413059, member: 94549"] [B][I][U]FINAL RESULTS ARE IN:[/U][/I][/B] After the brass was fireformed with the first 5 shots, I took the average of each test group and found the extreme spread, standard deviation and average velocity for the next 20 rounds fired. With all the issues with this brass, there still is a clear winner. I decided to throw out one shot that was furthest from the 20 shot average and get the SD, ES and average velocity. I continued to throw out the shot furthest from the original average for a total of 4 total rounds throw out of the 20 shot group. I will start with the worst method first. [B]5th place is annealing after 3 firings:[/B] 20 rounds ES 38 SD 11.2 2893 19 rounds ES 34 SD 10.5 2892 18 rounds ES 32 SD 9.9 2893 17 rounds ES 30 SD 9.2 2894 16 rounds ES 28 SD 8.7 2893 [B]4th Place no Annealing: [/B] 20 rounds ES 41 SD 10.25 2897 19 rounds ES 31 SD 8.25 2898 18 rounds ES 27 SD 7.13 2899 17 rounds ES 24 SD 6.7 2898 16 rounds ES 24 SD 5.71 2899 [/QUOTE]
