Guess I'm a bit out of line, then. Right off the bat, I thought of my "carry loads", way back in the 70's.

My idea was a 4" .44 Mag. with 180gr. Sierra Jacketed Hollow Cavities with 27.0gr. 2400 for the bad guys. Never fired one in
the line of duty.

I had those alternated with 275gr. Keith Style SWC loaded with 21.0gr. 2400 for engine blocks. They worked in all of the tests.
