Calvin,
Keep us up to date on the boob bag. I am having a tough time with the leather ear idea, but it used to be the normal. I did start with one, changed to cordura and liked it better.
Bill,
Making through the winter should not be a challenge for you, as you have made it thought plenty already, hell dirt is younger then you. LOL
Rob,
Not sure of what others may be using as an isolation material, but I have often thought about electrical shrink wrap (heat on style) as it comes with an adhesive built in. This would eliminate the possibility of movement from barrel to sleeve. Still the question is, will it be firm and thick enough to absorb vibrations.
For myself I have no planned projects, although I would very much like to test the tuner waters.
I will be ordering some carbide bushings for the .220 Beggs.
I still have a gain twist barrel that I would like to test.
