Make it a specially made 257 that shoots the 115 Berger at screaming velocities. A 27- 28" barrel with a McMillan and some great glass. Prepare to shoot many animals without using the stadia or turret adjustments. As you know recoil is very tolerable
My 257's trajectory at 4000 ft where we usually hunt coues wt.
Trajectory
100 2.8"
200 4.4"
300 2.9"
400 -1.9"
500 -10.4"
Drift (in 10 mph crosswind)
100 .3"
200 1.3"
300 3"
400 5.4"
500 8.7"
There are five of us that have taken a 19 coues wt with the above described 257. Many fold and don't even twitch, an amazing LR coues killer.
Also:
6 elk
4 mule deer
2 antelope
2 javelina
numerous jackrabbits and a few coyotes
PM me if you want to know the specifics.
