I currently have 4 loads of 9mm on hand.
The bulk of that is my USPSA minor power factor load, it's a 147gr coated lead bullet that I get at a very nice discount and results in under 10 cents per completed round. This load shoots soft and accurate in all my gamer guns, but I tend to not use it for practice in my carry guns.
The second is the same bullet and powder, at a reduced load, this is actually for my 9mm carbine, so technically not a pistol load (is sub minor in a 5" barrel)
The third is a hotter load using 124gr plated bullet that mimics a factory loading. I use this for practice in my carry guns.
The fourth only came about because I came across several thousand 115gr jhp for basically free. These are loaded fairly hot with a slower powder.
