Welcome Brock,,,nice to have you with us. Paul already gave you the info you need, I just wanted to welcome you. I too have a .22 XL and I love mine, absolutely fantastic hunting rifle.....
Clean the barrel really well if you haven't already, that should help end the smoking.... If that doesn't work then perhaps the seal is damaged and lube is getting in front of the piston,, in that case you know what to do. Mine stopped smoking after around 50 or 60 pellets.
