With a bullet that light, 50gr BH isn't really all that light of a charge. With the charge being almost equal the weight of the bullet you could pretty much bet the speed of that thing was well in excess of 2000fps. Considering 80gr charge will put a 250gr bullet to 1740. That much surface area coupled with that light weight would make it a pretty good varmint bullet out to 150 or so but I doubt it could buck any wind at all past that. I surely wouldn't shoot it at anything bigger than a coyote.
