I'll check the tang area. I had not heard of free floating it on a Savage. Honestly I have not messed with my other two Savages and they both shoot bughole groups stock other than a trigger job. I may as well hog out the bedding around the recoil lug and rebed it with only the back touching just to make sure. I guess it is floated from the lug forward? I usually bed 1 1/2" or so past the lug on 700's but you can't do that with the Savage barrel nut unless you would bed a small pad just ahead of the nut.
The reason I don't think it is velocity variation is that I have chronographed it with a different bullet and two different powders and the ES was not excessive yet it did the same thing with grouping tendencies.
Edge, the stock seems quite rigid and I don't think it flexes when it is on the front bag but that would be easy to check by moving it like you suggested.
Thanks for the tips, any other ideas would be appreciated as well.
