I have a CZ457 with a Dead Air Mask on it. I'm not having any trouble finding subs for it. I've been thinking about trying it on Coyotes at night but I only have one thermal and it's mounted on the .223 / Dead Air Sandman L combo (night coyote and hog). I'm just about through with my 8.6 Blackout build but the Dead Air Primal is a few letters of the alphabet away from being released, which equals about 9 months right now. The 8.6 will be shot in loud mode at first.
Here's a group of 4 plus one flyer from the CZ with subs. I shot one round and then attempted to hit the it with the other 4. I'm standing in my back door and shooting at a plate that I can hang that is 45 yards away. The 20, 30, and 40 yard hits are from a .357 mag. I was curious if I could hit "something" from that far away if necessary.
