Dirtfarmer,
Thanks for the info. Very intersting. I hadn't heard of Alpha Arms rifles before. Sounds like a fascinating setup and quite unusual. My 6.5 has a Douglas XX air-gauged SS barrel and it shoots superbly! Course, with as much as I shoot it and the velocity I'm pushing, it probably will need a new barrel sooner rather than later.
Any chance you have pics of the rifle? I'm curious to see it.
