Ron I read your post three times. But I don't understand. Why did you do this?? Were you wearing out the factory breech plug with 100 shots?? Is that what you are saying??

It looks like you countersunk the hole so the small screw would fit. That looks like a real nice job you did.

I assume by showing the nicked up bit that you are trying to say how hard the steel is in the breech plug??

How many shots do you get from the screw in place??

Just trying to understand. Thanks, Tom.
