[QUOTE="jdmecomber, post: 1385887, member: 94549"] Annealed vs not annealed I shot two groups of 5 This season has been kind of busy for me. I have been loading and shooting without double checking a couple things. With the previous group, I had the excessive trim length and also I was kissing the lands or a little jump in the last group. So these two groups I fixed that, The first group I shot 5 rounds of not annealed at .010 jump back to where I originally developed this load. I had some cheap factory ammo so I shot one factory round before the handloads. Not annealed 2-6th 2882 2871 2894 2892 2909 6th round opened the spread to 38ES SD 12 not so great. By not keeping up on trim length, doubling checking seating depth and not annealing. I had high extreme spreads and much higher velocity. Once the trim length came back down and seating depth was correct my velocity slowed but the spreads were still too high. I waited about 10 minutes, it was about 32 degrees outside. I wanted to make sure that I held the gun a little tighter back to my shoulder and tried to control the recoil as smoothly as I could. Annealed 7-11 2901 2898 2897 2913 2900 I know its a small sample group but wow. 4 rounds had a 4 extreme spread and one opening it up to 16 Extreme spread. I like that. Maybe custom chambers and the like would even get better? This is the RPR .243 [/QUOTE]
