I have a new toy (.257 Weatherby Mark V Ultra Lightweight). At some point I will probably reload for it, but for now will use factory ammo. As you probably already know there is a only a limited offering in this caliber. Most of it being from Weatherby. In looking at the home page, I found some information on their offerings. I'm considering the 120 grain Nosler partition, the 110 grain Nosler Accubond, and the 100 grain Barnes TSX. All have pretty similar ballistics. Any real experience with this caliber or these cartridges on deer and sheep?
