I have a Knight original orange disc rifle that I picked up with a rusty bore and had it relined to a .32 cal. 1;30” twist .010 deep by Robert Hoyt. I’m in the load development stage with this rifle and I’m shooting .315 RB with a lubed .024 patch, 25 grains of Swiss 3F, CCI 209 primers. So far it shoots ok but not near what I would expect. It seems to me to be excessive blowback in the breech area,from the threads on the BP to the chrome on the bolt after I remove it. I don’t know much about Knights but I know others on here are pretty savvy with them. Does it make a differance with blowback if the front ring/edge of the breechplug mates poorly to the shoulder of the barrel, something I have to check? Should I work on mating those two surfaces together for a perfect seal? Or should I upgrade to the newer style ignition for 209 primers. After shooting aprx. 30 rounds yesterday I noticed the breechplug was very snug to unscrew with all the crud. I use neversieze on those threads too.
Thanks, Magnum
