The more it expands the less it will penetrate. I assume that data is pretty much the upper level of .22 mag. 99 ft-lbs of energy strikes me as pretty limp. 125 grain standard .38 special from Buffalo bore shows:

Quote:
1. S&W mod. 60, 2 inch barrel - 921 fps (235 ft. lbs.)
2. S&W mod. 66, 2.5 inch barrel - 938 fps (244 ft. lbs.)
3. Ruger SP101, 3 inch barrel - 1019 fps (288 ft. lbs.)
4. S&W Mt. Gun, 4 inch barrel - 1078 fps (322 ft. lbs.)
The .22 magnum at its best does not seem even close to the .38 special.
