It all depends on the model and who made the pellet gun. I suggest that you re-post the queston with the model and make of the pellet gun to get an answer.
Gun shop or gunsmith
No recommended, Not designed for plastic BB's.
No it should not. Are you sure the air gun is a .22 caliber not a .25 caliber. Air you loading it right? Are you loading it through the breech? You are using an air gun not a real gun.
it depends on the model.
What an answerable question. You have provided oodles of information
yes! i did. u can put it in a barrel and go to the fort with the police and get it licensed
See the link below for the drawing.
If following the instructions in the owner's manual doesn't assist you, I suggest you take it to a gun smith/gun shop.
"The proper way to clean a gun is to make sure it is not loaded, spray it with cleaning supplies to get all the gun powder out and then put it back together."
look for pictures of the insides on google or nerfhaven.com and match your gun with the picture.
Oil it with "Crosman Pellgun oil", "RWS OIL" or "Gamo Pellet gun oil" Wipe it down. DO NOT USE Household oil or 3-N-1 oil. They will damage the gun. Put a drop in the barrel and run a swab through the barrel. If it's a C02 gun then put a drop of oil where the C02 bottle fits into the gun and charge the gun. If it's a springer type of rifle, put a drop of oil in the oil hole in top of the rifle barrel or in the loading chamber. DON'T over oil the gun.
