I have had great results with them in all calibers. I load them for 380, 9mm, 10mm/40, 45 ACP, 38 spcl, 357 Mag. I only shoot outdoors and the reason I bought them originally was they were on sale at one point. I like how they perform, the ease with which they load, and you can buy hollow points for the same price. I am not using them for defensive handloads, but use them in large numbers to replicate my defensive handloads.
