I do MO Concealed Carry Classes which require a minimum of 140 rounds (70 each, revolver & auto) and in the past, I furnished a .22 revolver, .22 auto and ammo for anyone who wanted to use them. If this ammo situation doesn't level out soon, I'll start requiring that students furnish their own ammo.
If they are using centerfires, I don't mind at all if they use reloads. Heck, I used reloads through the 800 round NRA Police Firearms Instructor Development School.
“Nine-tenths of tactics are certain, and taught in books: but the irrational tenth is like the kingfisher flashing across the pool, and that is the test of generals. It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex.” ~ T. E. Lawrence
