Is anyone out there shooting cast bullets out of their 450b AR 15s?
I am toying with the idea of loading up some HEAVY (395-400 grain-ish) cast bullets. Intent is to keep speeds under 1000fps. I build a 9.5" SBR a couple years back and it has become one of my favorite guns. I have shot well over 1500 rounds through it so far and have never had an issue. I am now looking to suppress the thing for shits and giggles.
what are your thoughts on the matter?
