I'm Not Sure...
I have been a .44 Special fan for over 40 years....just curious what everyones
favorite "working load" is.
Mine is usually 240gr. SWC with 6.8gr of AA#5
...what "working load" means but, if my memory is correct, my 240 gr. cast-bullets, loaded over 6.6 gr. of AA5, clocked around 850 fps and, out of a four-inch S&W 624 were a "shoot all day" load, similar to shooting a 158 gr. .38 Special load, at the same velocity, out of a K-frame revolver.
When I walk in the woods, during bear season, I opt for a four-inch 629, with 300 gr. bullets that are loaded in Magnum cases, around 950 fps.
