Don- YES, if I ever have any desire to shoot antelope. I don't really know whether your referring to African antelope or to pronghorn. Obviously, it wouldn't be ideal for pronghorn b/c it's a double and they don't shoot that straight after 200 yards. It's also not a "magnum flat" cal either. If your talking about African antelope, I would absolutely use it ont hem. It'll cause less meat damage than most of these guys' 270 mags.
To be honest though, I'm not real sure yet how it's going to work out. I'm working with loads etc to try and stretch that sucker out a little. I'm good within 175 yards witht the 286 grained bullets (what it was regulated with), but am trying to see if the regulation will hold firing lighter bullets. It's been a mess dealing with the regulation from just adding a scope, but things are looking up.
