So I took my NEA-22 out shooting Saturday with a buddy. The first test fire with the 9" NEA barrel went great but Saturday went to hell. After a little more than 500 rds and not being able to shoot a decent group with Blazer, my buddy was shooting when a round had a case failure. The case stuck in the chamber due to excessive powder fouling, the rim blew off and blew the extractor and plunger across the hood of my truck. After looking at the target I noticed most of the bullet holes were key holed. I used a small flashlight to try and get a look down the bore but couldnt make out any rifling, after getting home and using a proper bore light I found it was leaded like a son of a #####. Worst Ive ever seen, factory ruger 18.5" barrels arent anywhere near this bad after thousands of rounds. Anyways I soaked it in wipeout over night and tried to run a bore brush thru it....now the f**king bore brush is stuck in the bore. I am not happy... Does anyone know of a gun cleaning product or wicked California-banned home brew that will remove the lead without patching/brushing?
