You should try and find another .257 Weatherby Magnum (Weatherby Vanguards are a good value). They work well for animals bigger than pronghorn. I used mine to take a buck this year and it worked perfectly. Granted it was a shorter range kill, but the bullet did it's job with flying colors. It's flat trajectory and low-recoil help even novice hunters shoot with confidence. Zeroed at 225 yards lets you hold right on to a coyote from zero to about 350 yards. This greatly increases longer range hits on fast moving animals when you don't have time to use a laser range finder. The lack of recoil also mitigates the flinch factor associated with the big magnums, yet you get adequate energy for deer (or zombie) size game out to 500+ yards. Again, shot placement is paramount on longer shots, but the low recoil and flat trajectory are in your favor.
Then again, you have a .308. If you know the bullet drop, that cartridge can do anything a .257 WM can do and more.
