My first antelope taken in Douglas Wy. with my first wildcat cartridge and rifle - 6mm-284. I took the shot at 433yds with a 15mph 3 o'clock wind. The rifle - Weatherby Vanguard rebarrelled with a 1 in 9" 26" Pac-Nor. The cartridge - Nosler brass(6.5-284 resized), OAL is 2.874, CCI Br2 primer, 54gr of RL 22 pushing a Berger 95gr VLD(still waiting on those 90gr Accubonds) to 3600fps :twisted:. I also took a doe at 300yds. Excellent bullet performance, both antelope dropped within 10ft.
