Question- just talkin' basic on-site ready locker, not fancy Crimson Trace night shoots or gun skoolz, what would be considered "standard supply quantity" in the ordinance bunker at Roseholme cottage? for the "serious" stuff, not nessarily the odd-ball collector's stash...I have ".30 cal" ammo cans for .22LR, .32 H&R Mag, .38 Spl, 9x19, .44 Spl, .45 ACP, and 5.56 that I try to keep at least half full of general purpose range ammo. I start getting itchy if there are less than a thousand rounds of deuce-deuce on hand, so I keep a couple 500-rd bricks of cheap unplated stuff stashed away for a rainy day (like the Great Ammo Drought of '09.) That's twelve magazines through the 22/45 a weekend for two months' worth of range trips, which should keep me going until shelves start to refill.
As far as the two real calibers I use, 9mm and 5.56, a few hundred rounds of real ammo for each is set aside, in addition to whatever plinking ammo is on hand at the time.
