get a product called Kroil
best damn penetrating oil known to man
tried to take a barrel off a turk mauser
even tried a 3ft pipe wrench to no avail
put some Kroil on it and five hours later used a strap wrench to remove the barrel
made me a believer
I saw some at the gunshow last weekend and meant to pick up a can, never did so you see the fix I'm in now.
It's not a "darn need to remove it yesterday" type of thing but I'd like to do it sometime over the next month or three.
I wasn't impressed with Brownell's choke removal tool, I ended up selling mine. You might want to try a little heat. I heat the outside of the barrel and then hit the ends of the choke with penetrating oil while the barrel is expanded. If you have a steel choke tube wrench put it in place and tap it with a hammer. It may take several tries,but it usually works for me. The only tubes I haven't had success with are the invector plus. I don't know what it is about them but those barrels usually end up being shorter and threaded for a different choke.
If you haven't gotten it out yet, like everyone else says, heat is a good way to break it loose. Shocking it by tapping your choke tool with a hammer is another good way to get stubborn things to unscrew. You could always put it in a lathe and bore it out, but that's probably more than you want to do :roll:
