That is awesome! I almost did the same thing as you! I ended up getting a ICOTECH GC300 instead. I had a predator app on my phone but it had an ad with it also so every time you used it the ad would pop up. I haven't had a chance to use it yet but I'm hoping to get out tomorrow, so far it sounds decent and gets my dog all riled up. I had it out in the driveway just a minute ago and it was pretty load.
He came in about 10 yards running a fence line. We were on the other side of the fence line. He never saw us but just started to pick up our wind and started to quarter away from us into the open field. He was on a trot so I put the cross hairs on the opposite side shoulder . Distance was about 50 yards. He dropped and flopped where he layee. As you can or cannot see it looks like a gut shot but the way the shot lined up the entrance shot did enter about the gut and exited the far shoulder.
Load was 100 GR Vol BH209 W209 Sierra 300 GR .458 with MMP Orange.
