Boy GB, I don't know if dumb or stupid either one fits THREE. Like you said maybe 2 in a rapid fire situation, but THREE? I believe that may fall into MORONIC! That's one son that has absolutely no business handling a firearm of any kind with out adult supervision. Even if HE HIMSELF is an adult.
I too have fired a lot of Blazer ammo, with no problem. My question was when was it bought, how was it stored ect. Every now and then you get a ringer I suppose, although I never have. The 3 in the barrel however, is something I have never seen before.
