does anyone know if the powder coated bullets are safe in a glock polygon rifling?

Go to cast boolits.com. , scrow down to( wheelguns,pistols and hand cannons). Then scrow (the truth about glocks and cast) you should find your answer there. also check out power coating at the same site , there's 2 or 3 days worth of reading just on it. Bottom line YES! remember (Fit is king) with cast bullets
