Not bad at all. Which shooting range are you at?
DO let you friend relieve his conscience and mahine some nice airgun bit's, it's the least you can do.
It does amaze me how often you can hand an airgun to someone after them watching you and you showing the EXACTLY how to operate it correctly, 1-2 finers on the cocking bolt/handle ... ... . Then suddenly their instincts kick in and they cycle it likes it's a 303 enfield that sat in salt water form years or such. Maybe suggest to your friend something really tough ;like a bolt action marauder as you know he will be needing a pre-charged rig.
Glad that fancy rig is working out for you.
John.
