My 257 Wby does best with 115 gr bullets.
Many owners like the 100 gr bullets for the very high velocity, which is what attracts most buyers to this cartridge in the first place.
The only 100 gr bullet that excels in my rifle is the Hdy Interlock. It destroys an awful lot of meat at such high speed on closer shots, in my limited experience.
I think the heavier bullets are a good match for this cartridge.
