I own several wby markV rifles and every one of them shot a bit better groups once I rebedded then with the receivers & barrels supported for about 3" forward of the receivers and the barrels free floated a bit off the stock forearm at least enough off the forearm to slide a dollar bill up to with-in 3" of the receiver

I don't own a Weatherby (and don't want to), but all my rifles are bedded this way except lastyear's rebarreled M98. Used a heavy, '06, 27 inch tube and full length bedded it. It shoots great. Too.
I am not a fan of either pressure points or factory bedding.
