[QUOTE="QuietTexan, post: 2451781, member: 116181"] So in general expanding the brass does suck down part of the energy budget and reduces pressure signs. That said I can normally find a load on the lower edge of a speed or vertical dispersion node and have it shoot well for a loading or two before shoulders start bumping. If you're laddering up go ahead and find the top again, but I'd rather shoot a decent, well-shooting load instead of trying to run it hot. Cases grow either way at any reasonable pressure level. Let it level off, then do the serious stuff. You're already on top of the biggest issue with the 7RM, not bumping the shoulders at all until they grow. 👍 [/QUOTE]
