Just a small comparison with three calibers and a Barnes bullet suitable to kill deer and light enough to be fast, that I could also be able to find data for easy
.257 weatherby 80 TTSX @ 3800fps max. point blank range 406 yds.
6.5-300 127 Barnes At 3435 fps max point blank range 379 yds
.30-378 weatherby 130 gr TTSX at 3800fps max. point blank range 403 yds
all figured using Barnes data and JBM ballistics calculator set for a 4" radius of vital zone and 4000 ft elev. and 40 % humidity at 59 degrees
A 100 gr TTSX may get the 6.5-300 closer to the other two but it is all close enough to not care.
My personal choice is a 147gr ELDM out of a .260 that is stupid accurate and turn dials on my SWFA, Because elevation is easy, wind is trickier here all of the above will blow around like varmint bullets.....
