I had a friend send me a 100 lubed .402 sized bullets to try in my factory Glock barrel. Leaded like crazy after about 10 rounds. BHN around 20.
I took and boiled lube off. Soaked in mineral spirits and used harbor freight red shake and bake. One full mag and barrel sparkles like new. The powder coat makes my bullet .405. Shot ok but haven't checked for accuracy at range yet. Just leading. Gun slugs around .4058. Should I size the powder coat back to .402? Hate to buy a $275.00 KKM barrel if powder coating will do the trick. Wanting to order a 200 grain mold from Al at Noe but am questioning the above. His mold will probably cast around 403-404.
