Lately when I shoot my 22 LGU smoke is coming from my compression chamber when I open to load a pellet. I have not cleaned the barrel and it's not dieseling. Anyone had this happen to them?
Are the pellets lubed? May be partial combustion w/o full ignition. Does a patch come out with spot??
It would still be Dieseling .... Tho only at the point in the power stroke of piston where it just is bottoming out.
When you have full on dieseling the combustion of oils fills the barrel and even discharges smoke. Crack action open you can blow in barrel at breech and see smoke roll out of muzzle.
When the dieseling occurs only in the last moments of compression the pellet is on its way as is the air propelling nearly absent of smoke. Tho as you break the action open to re-cock there is a slight residual remnant of a minor dieseling event when the junction of Comp chamber to Barrel is unsealed.
As you further cock the action air is being drawn in threw the transfer hole and any residual smoke is sucked back in. Tho you may smell it.
JMO ... sharing thoughts.

Probably lubed pellets, I shot my .22 Cal. break barrel yesterday using FX brand pellets and was getting smoke out of the chamber with every shot but it wasn't Dieseling, FX pellets are lubricated, today I shot the same gun with HSN field & target trophy pellets and got no smoke, it's nothing to be concerned about.
