+1 for what's already been said about the 45 - quite hot, but very reliable in my HK USP Compact, my Para-Ordnance P14.45, and my girlfriend's Ruger P345. The P345 is junk with any ammo, and it stovepiped a few rounds (as usual), but the other two were flawless.
Definitely noticed a difference shooting it in the USP Compact - hot even compared to Hydra-Shoks, but not unpleasantly so. Also +1 on the dirt... but for the price, and the fact that it was the only brand of ball available for a short time in my neck of the woods, it was good stuff. And, as mentioned, the brass is great for my reloads.
