I am new to handguns and started buying from re-loader. I shot a couple thousand 9mm rounds of his stuff and every round fired perfect. I bought a 1000 online recently from a different outfit and got to take a couple hundred to the range today. 2 of them jammed the #### out of my nice shadow. Had to strip it down and pry the round out of the barrel. LAME! Whats up with this?
