Need some help guys, just purchased a new custom 6mm creadmore for coyotes and deer. 75% of my coyotes are killed under 100 yards and 75% of those under 50. But that 25% that hang up 3-600 yards I need to be able to kill as well. I've got Burris eliminator 3's on my other coyote guns and they are awesome except their low light performance is lacking. I've been considering the vortex viper in 5x25 or leupold vx6 4-24. I'm sure there are other good options as well. Your guys's thoughts?
