Major OOPS - he's using a 100 gr Sierra BT spitzer (thinking Gameking)
>>you need a better bullet like 100gr.Nosler Partition,Swift A-Frame,Barnes bullet those 100 grain sierra bullets will blow big holes in animals or just blow up and not penetrate well. trust me i have been shooting 257 Weatherby Mag.s a long time use a better bullet
+1. If you plan on big game hunting (and why else would you shoot a 257 WBY?), then you are going to want a tough bullet to deal with the ultra high velocity, at least at any sane distance.
