I did an informal test of this round and have ruled it out as a carry load. I set up 10 half-gallon jugs of water in a row and fired. The bullet stopped in the third one with an indent on the back of that jug. By comparison the Winchester 130 grain .38 (these are both Walmart ammo) penetrated 9. The +P 158 grain HP .38 does 6. I know this was a very limited test but to me it suggests that high velocity reduces penetration. With the .357 there was all the flash and recoil indictive of that caliber. Any comments would be appreciated.
