Only thing I can add is to soak everything down with Kroil for a few days before the Fire and Ice treatment begins. I had one that I thought I was going to ruin the barrel and action trying to get out and it popped right out after heat & cold plus Kroil. It was entirely re-usable. I have done the hatchet job and it creates a lot of clean up work the previous method doe's not. So I say F+I+K it.

"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
