I don't know. If you are a cheap *** like me you can do it for a lot bigger savings than buying factory. For instance 45 ACP, got brass from people who were shooting but not reloading a.k.a "FREE." Brick of CCI LP primers at Cabelas $34.99 - $34.99 Cabelas points = FREE. 1 lb of W231 powder Cabelas $24.99 - $24.99 Cabelas points = FREE

Lead ingots approximately $1.00 per lb. 1lb = 7,000 grains
7,000/ 225grain RN approximately 30 boolits.
$1.00 / 30 boolits = roughly $0.03 per boolit.

So lets total it up:
Brass: $0.00
Primers: $0.00
Powder: $0.00
Boolits: $0.03
Total cost $0.03 per round (minus labor)
Factory WWB $39.96/100 = $0.40 per round.

Okay, so no time for casting lead. So you buy 500 rounds of 230gr. RN Berry's Plated direct from Berry's. $70.88/500 or $0.14 per round. Maybe you still want to shoot lead, so you buy 500 rounds of 230gr. RN cast boolits from Missouri Bullet Co. $43 + $13 Shipping = $56 or $.011/round. Still less than half the cost of bulk ammo, if you can find it.
