Since it is a modern made rifle, perhaps you can find an owner's manual on line or ask around for someone that has one that would photocopy it for you. I would think it would say something about the sorts of ammo you can use safely. I would not trust any combination of bullet weight and velocity to be safe any more than I would use those parameters to solely determine a safe load for a vintage British shotgun.
