Personally if it were meI wouldn't shoot it period. If you insist on shooting it I suggest making sure it's still in time.If you're not sure how the timing worksask someone who knows.Even after making sure everything is still operating like it's supposed to Iwould not shoot the high velocity through it. I would stick with the Standard Velocity.In a 22LR revolver you can safely shoot the 22 longs and 22 shorts.The RG's are nothing but a pot metal revolver with very poor quality saying it mildly. I lived in S.FL years ago and know exactly where RG was located.Their quailty and workmanship was so poor even local gun shops would not carry RG's for liability reasons.Probably not what you wanted to hear.Like already suggested if you shoot it make sure you have safety glasses on and no one is standing to the side of you.
