I bought a Knight Bighorn this year and hunted with it for the first time this week and am having a problem with the primers falling out. I had at least four times during the weekend that I looked down and the 209 primer had fallen out of the breech plug and had to be replaced. Obviously this is unacceptable because I need to be able to rely on my gun if and when that big buck shows up. Has anybody else had this problem? What can I do about it short of superglueing them in.
