I think you would see exactly the same results with a 6.5X55 using the 156-160 grain round nose, soft point bullets or the 9.3X62 using the 286 grain soft bullets. It is what they do, and do well. I know I have on elk, moose, and grizzly bears. I realize however a Sambar is much tougher than a grizzly
Conversely, if we were to take that same 220 grain Woodleigh and drive it to 3,000 fps and shoot that same Sambar at 40 yards, the wound channel would be wide and shallow. The bullet may not even make it through the shoulder muscles to reach the intended vital organs, resulting in a very nasty non-lethal wound. I haven't seen this with that particular bullet, but I have seen it with other similar constructed bullets.
