This time a standard QRBP was modified to use the PRbullet adapters. This time JB weld was used to fill the fitment mortice. Somehow there got to be an air bubble in the JB weld, which i discovered the next morning when i started cutting the stuff with my pocket knife.












Then when i started sanding the JB weld to make it flush with the breech plug, i found i had cut too deep, and left a groove, so now there is a groove, and an air bubble











Because the plug was not going to use shotgun primers, the flame channel was made quite short, and there was only one vent liner with a 0.035" flash hole around here, so that was put into service.














The diameter of the primer socket was enlarged, and it was made deep enough so an o-ring could be used under the adapter.














This morning the Optima with the 4X scope was taken out to shoot.











There was very little breeze, so it seemed it might be worth a try at 200 yard. However, up where a 200 yard shot can be made is a ridge top, and there was a good right to left breeze. The elevation dial was turned up 8 moa, and three shots taken, one completely missed.











At home a couple more photo of the dirty breech plug.
