"Example 470NE is $220 per 20 rounds! Even handloaded it will cost you $100 per 20 to load it yourself"

What!?

On this very forum, I bought 90 once shot federal cases for $1.00 each (8 reloads / $1.00 = $0.12) and shoot Cast Performace heat treated lead bullets @ $0.32 each and 77Grn R15 at $0.22 per shot.

.12 + .32 + .22 +.01 = $0.67/per shot

so

20 * .67 = $13.40
