I just bought some range brass from Top Gun via Gun Broker. I received it today and immediately decapped it. I was bored. There were 20 or so cases that went into my Frankford Arsenal Decapping Tool tighter than the rest of the brass. I easily decapped them by easing the nut back and opening the collect up a little.
So, these cases were just a bit bigger toward the base. Almost all of them are simply stamped with a T and 5.56x45. Are these possibly bulged cases? They taper from the neck to the base. It's not an overt bulge. Could they have been fired in a rifle with a looser chamber? Perhaps they were just hotter loads? What says the INGO braintrust?
