I bedded and floated a 243 that shot poorly (3-4" at 100 yds). It was near MOA afterwards. The forend is very flimsy stock on those though; it required leaving a lot of clearance otherwise gripping the forend caused contact which hurt accuracy. I roughed the bedding area up with a course carbide burr in a dremel type tool. It left a very rough 'hairy' finish that the epoxy stuck to.
