$24 per 100 is $240 per K. $75 primer cost, 4 gr of powder @ 7000 gr per lb is 1750 shots. $25.70 will be the powder cost. Berrys plated $120. Total $220.70. Not much of a savings unless you are a home caster. Bulk lead trades at $0.83 a lb. 18 lbs gets you 1008 bullets. Basic cost for home cast bullets less time and equipment is $15 lead + $26 powder + $75 primers $116 per K.I know this is an old thread, but wanted to add my 2 cents.
I've reloaded 9mm since I started shooting it back in the 90's for my 39-2. Through the years (decades actually) I've learned to buy cheap and stack it deep! I still reload 9mm @ $5/box; $10/100. Cheapest factory is $12/box; $24/100.
Primers now are about $65-$75/1,000 and powder about $45/lb. Not sure it would make sense to load at those costs and have to buy the equipment too. But when ammo isn't available off the shelf, you can still shoot if you have the components.
