Primers run about $14 per thousand at local gun shows. I can pay a little less if I buy 5000 and a little more if I can't wait for a show and have to go to a shop. Good 9mm bullets are around $40-$50 per thousand, less if you settle for cast lead and more if you want to load JHP's. Powder costs vary, between about $8 and $22 per 1k. Brass can be collected/hoarded/scrounged for only your time, or bought on eBay for about $20 per 1k or less.
So that's
$14 (primers)
$45 (bullets)
$12 (powder, based on a typical load)
$20 (brass)
---------
$91 total.
Buy primers in bulk, use an efficient powder, pick up your brass, and you can get that down to $68 per 1k still using jacketed bullets. Use plated or cast bullets and you can pinch a few more pennies yet.
None of this takes into account the cost of equipment, or the value of your time, which are potentially very real costs. Basic equipment is quite cheap, and the nicer high-volume presses will last many years, so the cost of equipment will be amortized by the savings on ammo (especially with as much as you seem to be shooting!). Further, what most find is that reloading is almost as much fun as shooting, so the effort that seemed like a cost becomes a benefit. And with a good progressive, that time expenditure, whether "fun" or "work" will be minimal. You ought to be able to turn out an entire
case in 3 or 4 hours, tops.
9mm is one of the hardest calibers to "turn a profit on", so to speak. If you stick to your P99 or to 9mm's in general, you may never see reloading as worth your while. But the minute you buy a .357, .40, or .45, the ammo costs are going to hurt much worse than $11 for a Walmart 100pack. If you get the hang of reloading now, your wallet will be able to accomodate a much broader spectrum of shooting enjoyment now and in the future.
