Clancy, mine is on an EH3 at the moment, but I have an EH1 elite tac Moss ordered. As for the 80.5's, Jon will confirm that a metric poop load of coyotes have gone down in their tracks to 80.5's from his/TOM Ross/Mike Luckett's/ Rex and Woody's 22x47's. I hit a yote in the chest that was qtring to me at 104 steps, and it flipped her up and back. When I did some forensic investigation, the bullet grenaded and never even made it far enough back to punature the diaphragm. Everything dumped in the thorasic cavity and it was a lovely shade of red and purple jello. I have also killed a couple of big feral sows that ran about 200lbs each. Broadside Shots at 299 and 306, back to back, with both of them shot square through the shoulder / armor plate. Neither one took a single step and only one of them kicked about 3 or 4 times and that was it. DRT. I would have no issues about shooting a whitetail with it out to 300 or 400yds. If you wanted a bullet with a little more explosion, try a 69 or 77 Sierra TMK. They are proving to have a thinner jacket at the base of the poly tip than the classic smk does at the meplate. Guys are having very good luck with them out of 5.56/223 AR's over on the Predator Master forums.
