Chet, How does the trigger on that Mountaineer compare to the triggers on your other Knight rifles?
As far as the free floating barrels, I have had people tell me both ways. Some say free floating is best because changes in heat and humidity won't cause a difference in stock pressure against the barrel. Others I know add some bedding to the end of their stock to intentionally put pressure on the barrel. I guess I think you just do what works, I have sanded down the stock when it was hitting one side of the barrel and not the other and that has helped for me. If a gun wasn't shooting the best putting some shims at the end of the stock to put some pressure there might be one of the things I would try.
One more thing. How do you like your new Mountaineer Chet???
