For the hunting guns , never had a problem and he would always but random shit just in case. Honestly my dad would by almost any ammo if it was a good price.Cant argue with his logic....other than he maybe went light on ammo!
For plinking/blasting/target
22lr I dont think there ever was a time there was less than 30k on hand.
30 carbine always several cans if surplus
Several thousands if rounds of 222 and 270 which we used for target shooting and varmint control.
Shotgun well lets say I dont ever remember my dad actually buying any and I gave the last of 1000 rounds of “birdshot” and 250 slugs away that was still around from the 80s to my most active hunting friend.
Trap shooting. I started teloading fir trap when I got into active ATA shooting and was shooting more than 1000 a year.
All I can say is there is no better time or reason to get into reloading.
Sure might be a bit of a challenge finding your components but once you do stock it as deep as you can. You can by 1000 rounds of X or spend $1000 on a modest set up and enough components for over 1000 rounds.
