I use
these bullets for low-cost plinking ammo. I figure they're costing me 13 cents apiece at today's inflated lead prices.
I use Berry's too, and if you make an order large enough for free shipping, that drops the per-bullet cost down to a very manageable price.
For the lowest cost ammo, I cast my own bullets. Lead is still fairly easy to scrounge and because it's a hobby, we don't consider the time or effort as part of the bargain. (I'm trained in cost accounting and understand that nothing is free, but what the heck). When you cast your own, after you amortize the cost of the mold and melter, you can get the price of ammo down to the cost of primers and powder. I figure my .45 ACP ammo costs me 1 cent for the powder and 2.5 cents for the primer.
Ain't reloading grand?
