OK I redid my homework! I can not find anything conclusive that tells me which one is faster or not. If you look at the weatherby ammo using 200 grain bullets, its faster then the 200 grain bullets by remington. But if you just look at remingtons ammo, they make the ulta mag faster then the wby. If you reload, It looks like you can do darn near the same with either caliber. The weatherby is more expensive. I still love my weatherbys, they are the king when i reload um!
