So here you have the ultimate numbers:
B.C. .390-.453
Bullet weight 115-120 grain
Velocity 3000 FPS
What those numbers make you yawn? They don’t approach many of today’s modern cartridges.
Well record book Pronghorn and Rocky Mountain Sheep and several Mule and Whitetail Deer, Javelina and a Black bear wish I had never discovered the 257 Roberts!



That's a sweet spot, for sure. (PS: Don't tell Stick!)
