I own a .375 Win 94 XTR and love it. For Sambar (bearing in mind I have never shot a Sambar) I would say it was capable. But probably at the skinny end. So good for juvinile and does, but perhaps not my first choice for bucks. Having said that I would take it after Sambar, but only if my .300 Win Mag was broken. Probably not the greatest rifle if shooting across a valley. One of the shooting mags (guns and game I think), had a .375 shot buck photograhed in a stream that had taken a few shots to put it down.
