I'm working on a 257 right now for the folks at the ranch we hunt in New Mexico. K.C.'s girlfriend was given one by her grandfather, it's a Japanese Weatherby that has seen some use but is in pretty good shape, the problem was when they went to buy ammo for it they got a major dose of sticker shock ($60 for a box of twenty) They bought one and shot it up in about twenty minutes getting it sighted in. I told them I'd be glad work up an all round load for them gratis if they would cover the component cost. I know you going to question my bullet choice NBK but I'm going to start with a Nosler 115, the reason I've chosen the Nosler is because I want the hand grenade effect of the lead in the front half of the bullet as it should make for some spectacular kills with the shock effect of the bullet when it is driven at the ultra velocities the Weatheby is capable of.
