Thanks everyone for your help. A little history, this rifle was made in 1981, I bought it used for its beautiful wood, yes I'm one of those loonies. It was a .243 Win. It shot the same as it does now. I wanted a .338, Dan Pedersen in Prescott rebored and rerifled and chambered her in .338. It does shoot fine for moose hunting, which I may never be able to do, but I enjoy trying to make rifles shoot better. I will check the buttstock.
On the foreend tip, it has wood built up there, I could see it could make the barrel unstable. I can take the recoil, it does rattle the brain a little. I had a Decelerator put on while it was in Prescott. What about those Hicks devices and similar methods, seems so complicated. I will try the foreend work.
I am trying to hold things steady from shot to shot. I shoot at my own range in the back yard from my own homemade cement bench, good rests etc. Thanks again for the advice.
