Hi all. Last weekend I shot 50rds of lead through my 1911 (first time I shot lead in years!) and upon cleaning afterwards, the bore was badly leaded. I went to the Brownell's catalog to look up the Lewis Lead Remover with a view to ordering the same from our favorite BoG supplier (out of stock unfortunately), but saw that Brownells recommends J-B bore cleaner to use with it. I saw some at True Weight a while ago at an atrocious price of P1.2k each. It appears to be a mild abrasive. Does anybody have any experience using this? My Xtreme Bore Cleaner made no impression on the leading. Thanks!
