He runs 3 browning BAR's with the thermal scopes and 1 bushmaster A2 chambered for 450 bushmaster setup with a gen 3 nightvision scope but he is about to get an R25 from remington to set up with a high res thermal for his own use. we didnt use the bushmaster a whole lot Rod dosnt really like it all that much but it was free. i shot my big boar with it though cause Rod needed some feedback to send to hornady( one of his backers) i wasnt at all impressed with it. in the video all it shows is the boar hittin the dirt the first time but the rest of the footage was cut out. the first round i fired hit him square in the left shoulder and he went down as you see in the vid, but after that he got back up.. twice! i shot him once in each shoulder and once in the neck, and still had to knife him. just goes to show how tough big boars are. i think the 450 would be a great round loaded with different bullets but imo the hornady flex tip sucks. i havent been very pleased with its performance on deer out of my 444 either.
