Finally got to go the range day, after having this gun for a full week. I was about to go crazy to shoot it. Well I got to the range and got ready to shoot a cap or two off to get things started, I put a Win 209 shotgun primer in and tried to close the bolt, surprise, the bolt wouldn't close and the primer only went down about 3/4 of the way ?? I could not take it out with a knife or a flat head screw driver. Bummer. I took the bolt out and got a pair of leathermans and got the primer out. Lesson learned, it was not going to take the Win primers. So I thought before I put the bolt back in to see if it would take any of the other primers that I took. Would not take the 777 primers or the CCI mag primers either. None of these would fit in the breech plug at all. So I tried to call Knight but it was already after hours. I will get a hold of them tomorrow because I know they will take care of the problem. I'm just really starting to go nuts wanting to shoot this gun!!!
