You can order the Knight rifles with a bare primer set up. I do not use the red plastic jacket.
If you are having hang fire issues with your Knight and you are using the plastic jacket with BH209, then that is the issue.
I am not sure which model you have? However, I have switched all my Knight rifles to the LRMP system. The brass module holds a large rifle mag primer. They are much easier to load for me.

I have never had a problem getting my Knight Rifles to shoot crazy good.
View attachment 352783This is a group from my UL. The bottom is a three shot group then a small adjustment and the top is a 9 shot group with arrowhead bullet, and 117 grn (volume) BH209. (.45 caliber UL)
My disk extreme .50 caliber shoots awesome with Furry 320 grn universal with max load BH209 and with 75-80 grns (volume) BH209 and 460 no-excuse bullets.
