[QUOTE="specweldtom, post: 162902, member: 2580"] 300; I have limited experience with factory Wby stocks and barrels, but if it was mine, I would start where I bought it, or call Wby. If it's shooting more than a 1 1/2" 3 shot group with factory ammo, they should take it back. If it will shoot 1 1/2" or better with any factory load, it meets their accuracy guarantee, and they won't help you. If the factory warranty is unacceptable or unavailable to you, I would Steelbed the action and about 1" in front of the recoil lug (fit a layer of duct tape to the bottom of the lug with a hole for the front action screw). Don't let bedding compound get into the screw hole, it is a blind hole, and will hydraulic the screw before the action is pulled down into position. Free float the rest of the barrel and try it. It will change the rifle. Maybe better, maybe worse. If nothing you shoot through it is acceptable, put enough layers of about 1" wide duct tape in the end of the barrel channel to preload only that spot. Experiment with different thicknesses by adding or taking away tape layers. I don't like pre-loading stocks, but that is an accepted way of settling the little skinny barrels down. If that works, cut away all of the tape except about a 1/8" wide strip front and back across the channel and bed the gap with bedding compound for a permanent preload pad. (BTW, there is another method of pre-loading using the front sling swivel screw spud). Unfortunately the impact point will probably move around with changes in weather, pressure on the stock on a rest, and as the preload relaxes with time. If it's still unacceptable, rebarrel it with a heavier barrel contour, and consider a better stock. The Weatherbys are worth spending some money on, and the .257 Wby is a fine cartridge. Oh yeah, if you have the 2 pc floor metal, the 1 pc is better. P/M me if you have questions. Tom [/QUOTE]
