There was no shortage of ammo primers power or heads from 68 and on until we got nut jobs in the government, even with the Vietnam war going on, l was chuck hunting and loading in the late 60s then got into Bench Rest Shooting in the early 70 until 80s, l still have some empty power cans IMRs Winchester 748 & Hogden H380 from that time with price labels $3.75 to $4.50 lb, heads the same except for match heads grade one box Sierra 52g match from that time sitting on my shelf $7.46pr 100, have a 12lb keg Rem. 700X l paid $35.00 that's just under $3.00 a pound about 5lbs left us it now for my Marlin 1894 n 357mag., off the top of my head l can't remember what l paid for primers but they were cheap maybe around 2 cents each, back then all readily available at most good gun stores in NYC and NJ. l have been through the good time and now the lean time for the last 10 years but at 80yrs l'm still able to shoot but not as much as l would like to can't afford it.
For me, there is more going on than what we are told.
