Try to avoid using the grip tool Bob as they can snap off!
Metal into plastic is not a great idea.

Mark you may know that the Crosman Cowboy has a removable cylinder which is easy to do and makes a jammed pellet not the problem it might be in other models.
It’s also fun to to do it for no reason.

I like the Crosman but I would advise use of Crosman or Umarex co2 capsules as others can fail to pierce properly or at all.
I also think it is better suited to bbs rather than pellets although you get both shells with it.

Good to see yours has arrived Gareth.
Bet you get a pellet one too!
