You only shoot 9mm? Wow, you need more guns.
It was a lot easier to see the savings for me to start reloading.
Having 38 Special/357 Mag, 44 Special/44 Mag, 45acp, as well as 9mm, ammo costs are considerable. I never had more than 2 or 3 boxes of 44 revolver ammo on hand because of the high cost. Now having over 1000 44 Special and 44 Magnum rounds on hand, ready to go, gives me a warm feeling inside. Also 45acp is the cheapest large caliber handgun ammo available, but still, reloading brings the cost way down. Plus being able to load light 45acp target loads, that are easier to shoot than hardball, makes it so pleasant that I now shoot more 45 than 9mm at this time.
I do still load 9mm at about $5.00 per box of 50 115g FMJ. If ammo prices ever come down that low, I may go back to buying factory ammo but, I doubt it ever will.
Precision Delta has 115 grain 9mm FMJ bullest available for $74.00 per 1000 shipped, if you order 2000 at a time. I always look for good deals for bullets, powder, primers, and brass. Deals can be found at gun shows, the internet gunboards, craigslist, even posted at ranges.
Buy in quantity, whenever you find a deal.
