Okay guys, I have an old pump-action Winchester that my grandfather left me a long time ago when he passed away... its been in a friends gun safe room for YEARS now until a few weeks ago when I picked it up along with several other of my grandfathers old guns. I did some digging on this old Winchester & found that in its condition it isnt worth much... not that Id ever sell it, but if it was worth a lot I wasnt going to shoot it either. Now that I know it isnt really worth anything Id like to start shooting it myself. Last week I detail stripped the gun down to inspect/give it a REAL good cleaning. Everything went well & the pump-action now is real smooth since getting out all of the MANY years of crud... correction, everything went real well except when it came to cleaning all of the lead build-up in the barrel... Guys, this gun has seen 90+ years of various 22 ammo & I have NEVER personally seen this much build-up of lead in a barrel! So far NONE of the cleaners/solvents that Ive tried have helped it much (Although I can at least see SOME rifling grooves mid barrel on down.)... & I made sure all of the ones I used had lead removal listed on them. I tried Shooters Choice foam Bore Cleaner, regular ammonia-smelling Shooters Choice & JB Bore Cleaner paste... Ive tried each of these for hours a piece! I even put a brush in a drill & tried that to clean the chamber area... no luck. Id like to get ALL of the lead out of this barrel so it can be inspected... Im a bit worried about chamber erosion as Im told (by my dad) that it had a LOT of 22 shorts fired though it over the years... the barrel on this gun lists 22 long & 22 short. So what am I looking for to get this lead out fairly easily? There has to be something out there... right now Im thinking of just taking it to a local gunsmith & pay them to clean the barrel out, which I may do if what I need to buy to do this myself is pricy, ya know? FYI, surprisingly this old Winchester still loads & shoots pretty well as it sits!
