the rifle comes with a test target they use norma factory
300grn for their test fire 3 @ 30 yrds and 3 @ 50 yrds.

The barrel is tight to come out you use the bolt by holding the gun up right and allow the bolt to drop by lift and drop action a few times with your right hand while holding the barrel with the other. hermann I think will not have one on hand there was only 3 sold in australia ,so if the other shop has one I would get it asap or wait 7 months if you place an order .
