I've been carrying the Buffalo Bore 140gr solid copper "short-barrel, low-recoil/low-flash".

At 1150-1200fps out of 2.5-3" barrels it's authoritative, but not punishing to shoot.

One detail I like about the copper bullets is they don't deform like some of the exposed lead HPs (Remington/Federal 125s) when carried in speed loaders or strips in pockets.

My all-time favorite .357 carry load was the 180gr Black Talon at ~1100fps. It was surprisingly mild to shoot and hit like a ton of bricks. Of course it's long discontinued, and there's no replacement in the Ranger LE line.
