I find the factory brake works bloody well really, still boots but nothing to cry about. 200's are going 3030 at muzzle. It went through but made a hell of a mess of far shoulder and brisket on exit. Fallow are light boned thin skinned buggers any projectile makes a mess so best to head/neck shoot em. I used elds on a few big reds and they certainly do the trick at any range. At that distance they were going 2050 fps
