I'm planning on 2, 1-8 twist pac-nor barrels. The weatherby will be on a howa action 28", and the wsm is on my old winchester shadow 26". Probably stick with the factory contour or slightly bigger on the wsm. I planned on having both guns throats set with the boat tail at the neck junction. I just hate to throw 1-8 on both guns and find out the 170s are thin and explode on impact or something and have 2 expensive paper weights.
Thx for the repies.
One more thing, should I skip the winchester action for the wsm and just use a long remington 700 to get my length or is there a long enough mag box for a short action.
