I started reloading in 1972, and started casting bullets in 1973. Some shops stocked bulk powder, which they sold by the pound for about $3.00. Primers were about $6 per thousand. Using home-cast bullets I produced .38 Special, 9mm, and .45 ACP for about the same cost as paying retail for .22 LR ammo.
My competition revolver has been fired at least 50,000 rounds, but has never had a round of factory ammunition fired through it.
Even at today's prices for primers and powder, reloading still makes sense for the person who wants to shoot regularly without breaking the family budget.
