Majority opinion on this round- speaking only of the Super Police version- was that it wouldn't penetrate car bodies, was too slow, was unstable in flight, and gave poor terminal ballistics no better than 158 grain RNL. However, that instability in flight, especially in a snub, might cause it to tumble upon striking flesh.

I'd really like to know the probabilities of that happening, because if it was 70% or higher, being hit with a long, tumbling 200 grain slug in the Super Police configuration, might equal or exceed the best results from modern hollow points regarding stopping power. This might be just the round for J-frames. Have any serious studies ever been made that a tumbling slug of this weight and configuration might produce superb one-stop shots?
