I was excited to try out my Rem VTR .223 on some long-distance dogs last week, so I set up on a field where I was expecting a 300-500 yd shot as the coyotes come up out of a creek bottom. I got going on my hand call (cotton tail) did a few rounds and then waited. As I am scanning the horizon for sign, I see movement to my left. I look over and there is this small female staring at me about 25yds away! I quickly dial back to 6.5 power and get on target - she still hasn't winded me and POW! I explode her heart with a 55gr Z-max. Haha - not really a challenge - but I'll take as many as I can get!
