Oh dear. That was a mistake. Household oils are a great way to screw up your gun. Get the shop to clean out your gun, and buy some Napier gun lube. Note to everyone: DO NOT USE ANY OIL WHICH IS NOT DESIGNED FOR GUNS. Phew.
Yea, they sure messed up its accuracy and im a bad shot to start with!! Local gun shop said a very light coat of white lithium grease should work fine, As for the spring and barrel hinge he said dampen a rag with normal oil and wipe them over leaving a very very fine coat on them. All seems to be fine, cocking quite smooth now, shoots a lot better too!
