I'm guessing this has been beaten to death in some old thread but after many Glockless years I'm going to buy several Glocks. (G22 and a G21 w G20 conversion)I'm wondering if hard cast, properly lubed bullets (I tend to use Lee tumble lube bullets) are OK to use in Glocks if a few lead-chaser JHPs are at the bottom of each mag and if a Lewis tool is used to keep the bore clean? I remember reading years ago they were supposed to be a no-no with polygonal rifling.. was that an old wive's tale? I didn't use my lead bullet loads in the G17 I had way back then, because of this. I'm planning on an aftermarket standard rifled barrel for this use but I'm also curious about the stock barrel and lead loads.. thanks in advance Wanna kill these ads? We can help!
