My local indoor range does not allow magnums - something about the backstop rated for 1300 fps - so I shoot .38s something like 10:1.
Didn't research the shorter casing "crud ring" problem and am now sorry I bought a .357 (that ring is one stubborn cleaning job)
. Wanted the versatility to shoot the magnums, but it's not worth extra cleaning effort for me.
May either trade my magnum for a 38 spec, or start reloading (light loads in .357 cases).
