[QUOTE="Forcedoutage, post: 1767296, member: 108448"] I ran RL 17. RL 26 and IMR 4831. I ran into ejector marks and high deviations with RL 26. 61.5 grains 3013 FPS with 139 LRX. RL 17 I stopped at 54.5 and 3039 FPS. High deviations but no pressure. 139 LRX. Had planned to change primers and retry. 25” Brux 1-9 IMR 4831 59 gr 139 LRX 3194 FPS clean cold bore. 3154 fouled with deviation of 7fps. Most accurate as well. Once fired brass Quality Cartridge Brass. New Nosler brass brought this velocity down to 3090-3100. After once fired it came back up. [/QUOTE]
