The more I learn (about hand loading) the more I realize I don't know. But I learn a lot here and on the "6.5 Creedmoor Forum". And in both forums we speak in civil terms even when we disagree and I greatly appreciate that.
For PRS competition I often hear that I don't need the Nth degree accuracy of bench rest shooters - that is until I get out past 800 yards - then I do need it.
I'm retired and have the time and patience (I've been married 49 years so have learned patience ;o) to do the best loads I can. That includes using HBN bullet and barrel coating, precision bullet seating for a consistent COAL, culling out way over and under weight cases, and, one of these days soon, buying an annealer to get more loads from my brass. So as I progress in this fine madness I'll hopefully find "a point of diminishing returns", where anal retentiveness at some point does not equal smaller groups. The day I begin lusting to measure bullet runout is the day I'll know I've reached that point.
Hell, I even have a Neil Jones precision gauge for sorting .22 LR and .22 WMR rim thickness into lots. Rim thickness = headspace in rimfire rounds and they do group differently due to this slight headspace difference. So, yes, I can get anal about shooting, even rimfire.
