I full-length resize (every time), since I use an expander ball while doing so to uniform my necks. My results are very consistent with single digit SDs, low ES numbers and more importantly, consistent results at distance.
Eh maybe i'm hijacking the thread a wee bit but this caught my attention. The ol' expander ball question. I use an expander ball in the redding type S but have often wondered if it defeats the purpose of a neck bushing. I've read the full wammy on this one, and am aware some folks order custom sized expander balls.
Groups look great (1/2 MOA at 1k when I'm not sucking). I just wonder if I'm leaving something on the table by not taking off the expander ball. I have't measured it, but it's on my list of things to clean up and make a decision on.
I get it could be defeating the purpose of using a specific sized neck bushing, but some part of me likes knowing the inside of the case mouth is properly uniformed/sized.
ehhhh monday brain knots
