Re: to full length re size or not?
My chambers are always SAAMI spec. This makes things like neck turning and precise bushing neck sizing somewhat superfluous. It also frees me from being unable to process 'standard' ammunition in my firearms.
I know this means sacrificing some accuracy, but I also find that such sacrifice becomes more or less lost in the background noise of other uncontrollable factors, as long as I am serious about maintaining markmanship basics.
I believe that an average marksman will default a degree of marksmanship error that often negates much/most of the painstaking effort many of use invest into our ammunition fabrication process.
Very few of us, myself included, are as much 'on the ball', as much of the time, as we'd like to think. There's good reason why people like G. David Tubb are Champions, and I'm not. They have far better self discipline.
While it's true that a great marksman can't shoot bugholes with less than stellar ammo; it's equally true that average marksmanship will seldom render better than average acccuracy, no matter what the quality of the ammo.
Dependence on luck is not part of the basics.
I pay close attenton to brass prep, and things like individually weighed propellant charges, but I have found that for me, and maybe many like me, there is a point of diminishing returns where painstaking ammo fabrication is involved; and that this point falls rather further short of where many of us believe our marksmanship warrants than many of us are willing to admit. What I do, I endeavor to do consistently, and beyond that I try to keep my obsessions on a short rein.
That's neither an indictment nor a criticism, but simply an admission that I'm willing to settle for a more realistic appreciation of my own capacities. Maybe I'm alone in this, maybe I'm not.
