Pronghorn hunt with a buddy last August in N.E. New Mexico. Two killed at slightly under 400 yds. I was shooting a 6.5-284 with 140 gr. SST's at 2,950 fps, he a Model 700 Sendaro in .270, 130 gr. factory ammo. Not much difference. Very similar performance. Both antelope DRT. But, they're that not hard to kill, just got to hit them.
