Re: Brass Rotation
I shoot less now, but when I was more seriously into organized shooting, I would buy my brass in a batch of 100 at a time, then shoot and reload it repeatedly until the season was done. Usually, it lasted at least that long.
Unfired brass from an event would be used up for between-match practice, so each match's brass was experiencing identical usage cycles.
The next year, I'd start out again with a new batch. Old brass would be loaded up as hunting/zombie fodder, or used for initial load development with different barrels/bullets.
Though I shoot less often and fewer organized events, I still (mostly) follow the same practice. My brass just doesn't get as much exercise these days.
I have some marksmanship 'issues' to overcome, and unless/until I do, organized shooting can't hold the same attraction for me.
