Just an FYI.

Excerpt from referenced forum:
"ALL SCANDIUM REVOLVERS FIRING MAGNUM AMMUNITION
WARNING: DO NOT USE MAGNUM® LOADINGS WITH BULLET WEIGHTS OF LESS THAN 120 GR. THIS WILL REDUCE THE POSSIBILITY OF PREMATURE CYLINDER EROSION."

Note, I don't have the subject revolver. I haven't read its manual. And I don't reload. I don't know anything about bullets pulling out and jamming up a revolver, but can understand it would be a problem if it occurred.

The above quoted excerpt regarding cylinder erosion seems to be the main reasoning behind not using magnum .357 ammo with projectile weights below 120 grains.
