Last time at the range I got an honest 1 inch wide by 3 inch tall group at 200 yards. I had some lock up issues, and I have re-done the hinge with a shim and it is perfectly tight now, so I hope it will be better. I won't have a chance to shoot it before I go to Arizona for a couple of weeks, but will take it with me and shoot down there, if it shoots right I will look for a Coyote to try it out on. Only bullets I have now are Hornady 20gr VMax's, but they make over 4,300fps, so that is what I will shoot. Larry
