On a related subject, I'm using the OCW method, and firing my test increments "round robin". I understand the reasoning behind it, but am questioning the real world efficacy. I find it disruptive, and potentially error prone, to have to change targets and POA with every shot, and I suspect it showed in my groups. I'm using a Labradar chrono, so no concerns with that impacting them. I fire 5 rds. per charge, increments are usually .3 gr. All testing is done at 100 yards. Any critique of my process, or ideas to improve it? Although not exactly new to shooting or hand loading, I'm only just starting down the rabbit hole of precision loading, I know I'm a careful, meticulous loader, but I also know I have a lot to learn. Thanks.
Brian Litz said that once in an interview, not saying I'm right or you are wrong. That's what's cool about all this is we all get to decide what's important for ourselves.
A couple winters ago I sorted a several thousand bullets from different makers to several parameters and found base to ogive and OAL were the only place to catch a variance on any of them.
OAL being the worst but then after measuring base to seater stem it was clear all the OAL variance was between the seater stem and meplat and under magnification it was pretty obvious it was the meplat themselves.
With all that being said like I stated above I sort to .001" on ogive and .005" OAL with the real benefit being I catch 4 - 10 freaks per 1000 that are way off from the rest. They get used as foulers.
Don't know if it matters but it makes me feel better.
