Slugged my Glock 20 barrel. .398 on low side and .402 on the high side. I just ordered the Lee 6 cavity TC mold which is .401. I'm hoping powder coating adds enough dimension to add some to it. Was curious of what sizer die I should order. Going to use a push through bushing from NOE. Any suggestions would help. Coot sent me some lubed .402 and they leaded the barrel pretty bad. No ones fault but mine. I stripped lube off and they come out about .405 powder coated. Hard to seat at that thickness. Just trying to keep from buying Lone Wolf or KKM barrel.
