ALL replica rifles from Italy are proof tested to specific CIP limits...you can find those limits by searching, usually in the sellors link or online.
Those limits are well within safe limits for the specific rifle and you can load to those levels. If the rifle is chambered in a specific cartridge it is safe to fire that cartridge...if it isn't chambered in that cartridge or to a lower level than what you desire, then let your level of survival instinct reign.
I have a very high level of self preservation that has kept my fat body intact all these years...so guess what I would do...you do what you want.
Luck
