[QUOTE="jdmecomber, post: 1412277, member: 94549"] Groups 1-5 are complete This is new Hornady Brass and 2 CASES FAILED! I have never had that problem before for once fired brass. Brass prep was unturned necks with a neck size only die with a bushing for about .004 neck tension. Berger VLD 105 with H4831 SC Test number 1 is 6 groups with five shots each with brand new hornady brass, Group 6 will have to wait for a new bottle of Tempilaq my bottle was very old and I threw it out. Group 1 AMP this is the group where two cases failed I am assuming the low velocity from those. Pics included 1 2858 ES 27 SD 10 2 2852 3 2879 4 2871 5 2871 Group 2 after 2 Firings 1 2884 ES 13 SD 5 2 2883 3 2896 4 2892 5 2886 Group 3 Torch 1 2866 ES 15 SD 7 2 2866 3 2881 4 2879 5 2881 Group 4 After 3 firings 1 2879 ES 15 SD 5 2 2881 3 2866 4 2879 5 2876 Group 5 no annealing 1 2882 ES 19 SD 8 2 2884 3 2901 4 2897 5 2885 I am going to throw out the two failed cases which I believe are the 2858 and 2852 It looks like 23 rounds had a 35 extreme spread and an SD of 9.2 Test 2 in progress [/QUOTE]
