Swifty,

I didn't say that claimed bullets "destabilize." I was pointing out that if a rifle groups well with certain loads at 100 yards (which is what country boy says) there's no physical reason the rifle itself will cause groups to open up at 200. So the answer has to lie elsewhere than the rifle itself.
