I have a Winchester model 70 feather weight in 7-08. Its a newer one, Morgan , Utah on the barrel. Heres the new issue. After mucho work on this iron, it generally is about a 2" gun. However, when it gets hot, the groups cut in half. This is with a free floated barrel, and same with a pressure point at the forarm tip. I never had one shoot better hot before. Any logical reason for this? Its repeatable. Open to sugestions.
