Long Barrel .22 Conversion

[sheepherder]

The first shot with the modified barrel & chamber plug, the plug backed out about 1/32"...Not good...

I took it apart and re-measured the plug and the reamed-out chamber. The diameter was right on, both OD of plug equal to ID of chamber. It was a tap-in fit. The length of the plug was .001" less than the chamber. The pressure from the chamber was forcing the plug to back out.

So, to fill in that .001", I dripped a couple drops of epoxy onto the end of the plug, and also deepened the setscrew hole a bit more. The next time it was shot, there was no backing out of the chamber plug. The gas leak was sealed.
