Hello, this is my first post on this very interesting web site, I hope you can help me out. I have been bush hunting Sambar deer in Australia for a long time now with my .338WM Sako Hunter and have always enjoyed great success, Most shots at under 200 yards. But recently I have started hunting a new area where long shots are the norm. Sitting on a ridge top and looking for deer on the other mountain. Shots from 300 to over 1000 yards are on offer and the stags in this area are huge! ie Elk size. My question is should I stick with my .338WM for this type of hunting or should I opt for a new rifle/calibre combination? If so what? Thanks.
