People are saying that a .50 autoloader rifle with a massive brake is not for 100 yards, but I would argue that disabling a vehicle at maybe not usually 100 yards but 300 is....feasible? Sure it can reach way further than that but it's engine block-shattering capabilities is what it's built for. With a low magnification optic and some practice you can easily do doubles on these guns. It's an autoloader, made for fast follow up shots. How far away are you realistically going to be able to hit a moving vehicle? Even if you miss the rotating assembly all you have to do is cause a loss of oil pressure and the vehicle will basically roll to a stop.
Who knows, you might have to one day shoot a hostage taker through a brick building at 50 yards so you should practice at that range.
