[QUOTE="Toons, post: 1694963, member: 111000"] Joe, I'm fairly new to reloading, working up a load on my RUM using the ELD-X. I've had very sporadic groups, starting with the 220, then the 212, and settled on a 89gr charge using H1000 and 3.6 COL, 3005 FPS off of a chronograph. I stopped at 3.6 since that's the limit of the magazine and the reloading manual, but decided to measure the distance off of the lands, and got a surprising 3.866". That's a huge jump compared to what most posts are shooting for, so I loaded longer rounds based on the Berger method and my group at .050 off the lands had 3 bullets touching out of 5 (1 of which I know I pulled). So, best accuracy is a 3.81 COL, which turns me into a single shot rifle. I'm fine with that for a 3/4" MOA vs double or more at 3.6 COL, but I'm concerned with over pressure. None of my cases look to be damaged. Any other signs I should be looking for? [/QUOTE]
