This afternoon, after two stands, I started back to another field for the last stand of the evening. As I stepped accross a fence, I saw a coyote out in an open field about 120 yards away. I shoot a remington vs 223 using federal ammo factory loaded with 50 gr. speer tnt hps. On my first shot, the coyote dropped and then started the "death circles". I put another round in him and he dropped and didn't move. Thinking he was down for good, I turned to get my pack and when I looked back, he was running accross the field. I managed to put one more round in him before he went into a cane thicket. I looked until dark and could not find him. What do you think of the tnt hps because after this evening, I am beginning to rethink my ammo. Also, what is everyone using in their 223s.
