Yes Wolfhound, I'm shooting the "red full plastic jacket" and did use some again and as you said, some of the primers do come out. I was having the same problem with new ones. I did find out that the primers have to be inserted as far as possible. My 11 year old was not pushing the primers all the way and almost everytime the primer seperated and the full plastic jacket was side ways. I even noticed with 2 new ones that the cocking mech. would almost recock itself on some shots. I have to admit the 295 grain Power belt with 80 grs. of 777 had a fair amount of recoil :shock: .
WD45, I haven't tried anything but 777. I may have to try something else as between the bad Encore barrel and the Knight, I only have about 10 shots left :eek: . I usually don't use a pound of powder in 3 years. Don
