I have a FWT in .243 that is finally showing promise and an extreme weather in 300 wsm. They aren't perfect but are much better than the patterns I ever got with my early 90's vintage 7mm rem mag (which I spent several hundred on trying to get sub moa). I like them! I really like the way they feed. This is particularly noticable with the 300 wsm. My Xbolt will sometimes bind when run on the slow side and fail to feed a new round. I have had no problems with the model 70 in this regard. The Xbolt is accurate enough but I'm thinking it will probably hit the road when the extreme weather is broke in.
