+P is nowhere close to 357. Not even 357 lite. Warmed up 38 special.
For hunting I use either a 158 XTP or a 358156 gas check and the max listed load of 2400 in my Henry single shot (deer). In my 6 1/2" Blackhawk the 357446 and 14 grains of 2400.
SD, factory +P JHP.
Tin cans, whatever is left from other projects.
