Dad used his Weatherby Ultralight in 7mm Wby Mag on an antelope hunt last month out in WY, scoped with a 3-9 Nikon with the BDC reticle. The rifle was purchased used on this site several months ago and I installed the scope + rings and set it all up for him.
First antelope was 800+ yards, second was 512. Both one shot kills.
Ammo was Hornady 154gr Interbond - factory ammo.
Just an example for you. And yes, the rifle is coming along on next month's elk hunt.
