Grouse45

I shot what might be the FPJ version this morning... virtually no hot blow back from the barrel at all the breech still got sooty from the primer blowing debris out around the plastic jacket + I was using WELL used plastic jackets. No collection of material on the scope at all and the bolt always worked freely.

I totally disagree with the brazing of the vent liner in the BP. I know you have your safety reasons, but I would like to be able to change vent liners on my command.

I shot 24 shots this morning (T7-2f) - removed the plug and screwed the vent liner right out of the plug. With the tape and the bit of aniti-seize not a hint of a seized liner.

And the most important part it shot very well.

24 Shots later...



Not quite as clean as the NFPJ that Grouse shot... and the material you do see is from the primer. And again I need to mention I was using USED plastic jackets (6 to 10 times used)

Bolt and primer cavity...



Under side of the scope....



What material you see here is left over from previous shots with this scope mounted on a Knight. If you look closely at the label under the turrent you can see discoloration occuring from heated blowback. This occured when shooting the scope on another Knight with a factory plug.
