[QUOTE="101stCurrahee, post: 1755181, member: 111731"] So many answers, so little time... So this (pictured) was just a sheer statistical coincidence? Here’s the rest of the info I shot 50 rounds through it new, Shooting once clean once 5x then shoot 5 clean once for rest of the 50. I then shot 30 more (in groups of 3 at different charges) working up my load where I shot the pictured group at 77 grains. At 77.5 grains it widened up, and I stopped at 78 grains even though I still had no signs of pressure. So at that point I had 80 rounds through. I then loaded up these 20 more that were garbage at the same charge weight. So now I’m at 100 total. How I started- 100 new brass from gunwerks. I trimmed all to within .001 of each other. I chamfered and deburred and then tumbled. I primed with cci #250s. I checked seating depth with a modified case and got 2.909 with my Berger 215s at the lands. I used a Hornady comparator for measurements. I then meticulously loaded as perfectly as possible with H1000, and seated the bullet at 2.889 for .02 off the lands. I followed this exactly for all the loads I did. The second test run was once again the new brass. I haven’t run through it all yet to mess around and alter after it’s fire formed. I sat at the same bench shooting off a sled for all but a couple that I shot off a bipod to see if it was any better. With my “good load” the first 3 of the 5 were still terrible. It didn’t widen up because it was a 5 shot.” I also had nearly the same ambient and ammo temps waiting the same amount of time between shots. The only difference was I had by chrono in closer a bit the second time, maybe that contributed to high FPS a bit too? My barre is not thin. It’s a heavy profile barrel. When working up my 10 3 rounds each loads it kept it as even with temps as possible. Besides the first group or two warning it up(which were 72 grains I had no intention on sticking with) I let it cool to roughly the same temps. All I did for load testing was the 3 round groups in .5 grain increments, shooting for raw accuracy groups while keeping in mind the vertical dispersion. I wrote down every single shots velocity and saved all targets and information. [/QUOTE]
