my buddy's grandpa died years ago and he eventually ended up with his CVA muzzle loader. it takes percussion caps, is 50 caliber and has a plastic stock. so the long and short of it. my buddies uncle (the man that gave the gun to my buddy) didnt clean it last time it was shot. the breech plug is stuck in place and despite soaking it in wd40 it will not budge.
we were going to clean it up good and then shoot it and get it ready for deer season for him. it's got really nice, fine sights on it and i like it a lot and cant stand to see a good gun just waste.
the bore is rusted as is some of the other parts but it will clean up well i think with only minimal damage. i just cant get the breech plug out. if it was hex headed i could use an impact wrench and socket. but it's just got 2 flat sides to use a wrench. the barrel is octaganal and so far i've tried clamping the barrel in a wooden cabinet makers clamp and using a large cresent wrench on the plug. as much as i turn it will not budge.
