Congratulations on you new Weatherbys. I've got a couple myself, a 270 Wby Mag and a 240 Wby Mag. I was very surprised how hard the 270 hits on a deer, and flat shooting, wow! The 240, what can I say, it is a definate sweetheart! A 300 yard shot with 95gr. Balistic Tip, no problem. Then load it up with a 70 Balistic Tip, well, let's say a coyote's not safe a quarter mile. I think you will definately enjoy those rifles.
Happy Hunting!
