found the answer:
“NO LESS THAN 120 GR BULLET”. This statement refers to .357 Magnum rounds only, not .38 Special rounds, and there is an interesting reason for this restriction. Magnum bullets that weigh less than 120 grains will exit their cartridge before the cartridge charge has a chance to completely burn. This charge will leak out onto the cylinder and frame while still burning, causing damaging oxidation to the gun’s exotic materials over time.
