I played around on MidwayUSA and got up to $1,488 worth of reloading supplies including Ground Shipping. This includes the RCBS kit, .45 ACP dies, .223 Rem. dies, RCBS shellholder #3, RCBS shellholder #10, RCBS Vibratory Case Tumbler, Corn Cob Brass Cleaning Media, and enough unfired brass, primers, powder, and FMJ bullets for 2,000 rounds of .45 ACP and 2,000 rounds of .223 Rem.
A cost comparison to 2,000 of Winchester 230 gr. FMJ .45 and 2,000 rounds of Federal 63 gr. .223 would be $1,818 include Ground Shipping.
The reloading supplies pays for itself and save me $330. That's just for the initial investment. After 4,000 rounds, I'll see real savings.
For example, enough primers, powder, and FMJ bullets for 2,000 rounds of .223 is $383. A cost comparison would be $1,080 for 2,000 rounds of the same factory ammo. $697 in savings!
It would take a long time for me to shoot thousands of rounds of .45 and .223 ammo, so I can spread the cost over a year.
Holy Crap! I sound like an accountant!
