Jimro, yes, its factory chamber, but have been told by other reloaders that when shooting for semi auto AR you must use small base dies. That's the only reason I was going to replace my FL RCBS dies. I have not used them yet so they are still brand new. Should I try to use them or just get the small base dies instead?
