A while back I picked up a couple of rem 700s in 7 mag. The price was too good to pass up. One is set aside for an Edge build and I'm wanting to build a lighter weight rifle on the other. I already have a 300 rum and have other 7 mags so I'm wondering what would make an enjoyable caliber to shoot in the lighter gun. I have never reloaded for weatherby calibers but the 257 wby mag has gotten my attention. What other calibers would you guys suggest? Thanks!
