The smallest center-fire cartridge that I shoot is .357 magnum.
While I have a 1978 Blackhawk revolver as well, I most like my newer Marlin 1894C in .357 Magnum.
- It's light, handy, short (18 1/2" bbl.) and traditional with two barrel bands.
- You can shoot cast bullet .38 special equivalent hand loads in it for fun and small game.
- You can shoot 1800 FPS / 158 grain JSP hand loads in it for whitetail deer.
A very versatile cartridge in a carbine.
They are very handy. I have a Model 92 357 lever that I use it for pests. I got a sale on 125 gr jacketed HP bullets many years ago. They aren't particularly accurate, but do quite well at short range.
