Re: .257 Weatherby with 90gn GMX
I am shooting the 100 grain barnes at 3760 fps out of the same rifle with 75.5 grains of magpro. 7828 got about 100 fps less. I would imagine the 90 grain GMX would be a lazer at near 3900 fps with the right loads. It should hold together well and kill about anything since it is monometal. I may try it in mine. Didn't know they made such a thing. What is the BC?
Predictions are difficult, especially when they involve the future
