I reload, and if you want to shoot more than 50 rounds per month, I'd advise you to learn to reload. Here's my cost breakdown.
Bullet 180gr. Berry's plated Flat point $0.13
Powder Alliant Power Pistol (I won't give load info, it's free online) $0.03
Small pistol primer $0.04
Used brass $0.03
Total= $0.23 or a box of 100 for $23.00
Cost of reloading equipment approx. $300.00, tough to amortize if you don't know how many you can make before it's worn out, but so many that I believe the cost per round is not affected in a measurable way.
Peace of mind in being able to shoot what you want, how much you want, when you want.
If you want to buy, Lucky Gunner will make it worth your while if you buy 1,000 rounds or more.
