Coxhaus
Time to buy a years worth of stash when supply comes around again. I was amazed how many didn't, many years ago when primer scare hit the first time.
After that we kept spare bullets, primers and powder and cases enough to shoot a complete year, and never touched it.. rotated yes, but never touched.
Thats probably why I have 100ish pounds of WC852 and almost 50 of N540 and I haven't even counted the SMKs laying around in .224 cal.
Good luck. BTW as you know, for short range, like 200-250 yards, a 125ish flat base even hunting bullet might work. I know Berger made something like that, that Nez used quite a bit for the real short range stuff like 200 and 300 yards.
