I will
austemper like the Soviets from here on out. I found a heat treat facility that quenches in a molten salt bath . Oil quench warped mine when I attempted that. See my "HEAT TREAT + latest build" thread for more info.
The mapp gas method worked for 3 of my builds, and with a few hundred rounds through each they appear to be fine. I screwed one up and started looking into other methods. After reading awhile I decided I wanted to do it like the reds.
If you can find someone in TX that austempers at a reasonable price I would do that. I did a few at a time so it was more cost effective. You could get several people to go in on a batch together if needed. perhaps put a thread about it in the Hometown forum once you have found a place to do it? I managed to get it scheduled so I could wait for it to be done before leaving.
