If wadcutters were the best choice, it seems testing would have revealed it decades ago, and the WC would have been adopted by large agencies due to the mild charge, low recoil, target grade accuracy, and lower cost.
Instead, the FBI finally settled on the 158 grain "FBI Load" (158 rain lead hollow point at +P velocity), and then finally, the 147 grain JHP +P. After using 158 grain LRN, then 158 grain SWC, NYPD finally settled, after extensive testing, on the 135 Gold Dot Short Barrel.
This topic comes up constantly here and on the "Snub Noir" site, and I often wonder if folks just want reassurance that what they carry will work.
So, if carrying a target load makes you feel more confident, it is a free country. For my purposes, however, what makes me feel more confident is a tried and proven load, and both the FBI Load (also called the Chicago Load or the St. Louis Load) and the GDSB from Speer both have real and extensive track records. I will stay with those, thank you very much.
Remember what Jeff Cooper said about the .45 ACP on the range at Gunsite: "we make no foolishness about using reduced power loads, we use only a full-power load, a fight stopping load."
Makes more sense to me.
