Another thing to check is the Luckygunner tests of 38 special and 357 Magnum.

357 Magnum gives significantly higher muzzle energy and better expansion -- even in 2" barrels.

It may be a bit slower getting back on target for a second shot.

That's a matter of practice. Shooting 357 Magnum requires more practice.

But if you score a well placed center of mass shot with a 357 Magnum you may not need a second shot.
