Nothing wrong with 357 Magnum ammo in a snub nose revolver if.....
you can handle the extra noise, heavier recoil, extra muzzle flip and
extra time to get back on target for your 2nd shot if needed.

I saw a slow motion camera on the snub .357 with a magnum loading
and it showed the recoil, muzzle flip, the rising of the weapon in the shooter's hold
and what surprised me, was the hammer actually going backwards from its fired position as to re-cock...........
from the amount of forces brought into the act of firing.

The cylinder flash, muzzle flash and bullet exit was........ neat.

However the 38 +P is also nice for many.
