There are over 50,000 rounds of both factory and reloads through my Guerini Magnus combo.I shoot reloads almost exclusively through a browning 725. Yes I know not a expensive gun but will continue to shoot reloads when I upgrade to a real deal high end gun.
All the manufacturers caution against using reloads.Basically the question concerns the shooting of reloads and the potential albeit perhaps small that an issue would
void the factory warranty as Caesar Guerini's manual for example expressly says not to use reloaded ammunition.
So if you shoot a high price gun your monetary risk is greater than shooting a lower priced gun and does that factor in your choice of shooting reloads or not.
