[QUOTE="timberelk, post: 1410772, member: 100952"] [B]UPDATE FROM OP... [/B] Went through the whole reloading process this morning and went out and shot (weather was 25 degrees with 15 mph wind from behind me). Groups were not great, my 1” group I shot last weekend shot a 2.5” 3 shot group. But I did try a 41 grain load I’ve never tried and it shot 3/4 with all this wind (maybe I found my best load?). Anyways I digress... I set my FL die up to push the should back .001-.002 and the cases each grew between .005-.007 in total length. I then trimmed them all to .025 (a few were trimmed a little too far to .022-.024) and put them in the tumbler. Then I loaded them all up and went out a shot them. I then measured each one and it looks like half of the cases stretched by .001-.003. A few stayed the same and a few appeared to shrink but those could be the ones that were accidentally trimmed to far to .022. So it appears that during firing (this was the 3rd time these have been fired) they only grow by a few thousands but when FL sizing they grow by .005-.007 resulting in me needing to trim each time because my total stretch is around .010 (.001-.003 from firing plus .005-.007 from the die = .006-0.10” approx stretch). I had to set my Hornady FL die to contact the shell holder plus 1/4 turn in order to bump the should back approx .001-.002 And I still got the same shinny/dull sections that started this whole thread. I’m thinking that the dull is where it expands to my chamber and the shinny is where the brass didn’t expand at all and still has the polished look from the tumbler media (see picture) Also in a side note I loaded a total of 9 cases with 38.5 grains of RL15 (starting load) with 150 ELD-x bullets. 3 were at approx .030 off the lands, 3 were approx .070 off the lands and the last 3 were at .100 off the lands. All shot like crap but the .100 shot the “best” [/QUOTE]
