Ok i tested it out at 100 yards. Accuracy was amazing. Blow back seems to be more but i know how to fix it.

The spacer sits in the cup i made but due to the drill bit i used, it left a cup rather than a flat surface for the primer to sit up against. Thats the problem! I'll make a new shim once i get some material to work with.

The O ring you see between the Spacer and breech plug is just a weather ring. Keep water and stuff out and away from the primer. I need to find one slightly smaller and then inlet and area in the spacer for it to sit in.

And on the new spacer this is the area i will have to cut FLAT. Thats whats causing the blow back.






Excellent accuracy though! 90* and no cool down time.
