I have a VSSF II in 22-250 that I turned into a switch barrel, with a 22-250AI barrel and the original, my only beef with the rifle is the bolt face, the firing pin hole has a bevel on it, which causes primers to crater, which results in hard bolt lift on every round fired.
Groups are very very good, so I can't complain about that.
Sorry to hear your woes with your rifle.

Cheers.
