RodentRidder,
I purchased a .308HB Survivor a little while back and have been working with it some, but don't have it satisfactory, yet.
I have not been able to make mine shoot well with the Survivor fore-end and I am just before ordering an Ultra Rifle 22MagHB, in order to have a replacement laminated stock and fore-end.
One thing that I will convey is that I think this rifle prefers flat-based bullets and not boat-tails. I'll report any progress that I find.
