I got a call from my boss (nameless to protect my job), who asked if I knew how to take a stuck bullet from a gun barrel. So I describe the procedure. He has no close fitting steel rod, and the "gun" is a Crossman .177 pellet gun.
So, I get on over to Brownells, and order up a .168 drill rod, which is as close as fits a .177 barrel (whose bore is about .172). It comes in, I get my five bucks back from him and hand him the rod.
He calls me back - no go. Hammering isn't working. So I ask him to measure using the rod from chamber and muzzle.
Reporting back - there are TWO pellets stuck. I asked how he knew. He said, the rod went in so far from one one, and another distance from the other, but there was a space between the two marks he made on the rod, so it must be two pellets.
How big a space? About two inches, he said.......
So I regret to inform him he has two inches of stuck .177 pellets in the barrel. On that, he said - you fix it!
So into work came the pistol, semi disassembled... bolt and associated parts out.
No go... there is a LOT of lead in there.
Back at my shop at home, I took the rod and got it into the barrel from the breech. Then... on the 12-ton shop press... I began pressing, and the rod started moving. Wonderful, except, the rod was too short, since it cut it to avoid it flexing. It was just long enough to go from muzzle to chamber, but not to the back of the action.
A variety of makeshift rod extensions got used, including various stainless screws that "just" fit into the action to push the rod.
What a worm of pellets came outta that gun... but then I started thinking... this press is under maybe six or seven tons of pressure, and its flexing a little.
I ran and got a pail, scooped about four inches of sand into it quick, and got it under the press. No sooner than I got it placed - kerrr-aaack! The rest of the pellets sprayed out the barrel, followed by the rod. Jeez man! Glad I was awake, glad I have my safety goggles on. The sand caught it all, and the rod stayed put too! Fortunately!
And, except for a little worn paint on the brass barrel - all is well in Crossman land. No bore damage I can see, no remnants or qweeb in the barrel...
A good repair!
And exciting.
And I learnt somethin!
So much for Friday afternoons off.....
