I got the Koplin gun boot and the bracket about a week ago and had the opportunity to try it out just this past Friday. I placed my Howa .223 with a 4X16 Bushnell scope on it in the boot, and headed off up into the hills behind my home here bright and early in the morning. Using an old power line trail up to a nearby spring where I've seen cougars, bobtails, and coyotes on prior outings, I set up between a couple of big boulders and waited for daylight. I used my injured rabbit call. Note: I didn't have any problem at all of getting my rifle out of the scabbard, and the subsequent, and only shot proved my scope was right on, even after going over some pretty rough terrain to get out to that specific spot. My shot was just about 150 yards (coyote) according to my range finder, and the 52grn Sierra bt/hp hit right behind the left shoulder as directed. Anyway to make a long story short I do believe that set up is going to be just fine, when I head up to Flagstaff area for elk this December.
