This is a great way of doing this! I have used this method often through the years in multiple circumstances. A little time consuming, but I always felt very confident in the results.

I finally got it to where there was some resistance closing the bolt but was not tight or hard to close. I’m hoping that after annealing and forming the false shoulder, I’ll be in business.
