The 300 Win(Wea) are both excellent rounds! I've taken many larger bodied game with the 300 Win (moose, elk, caribou, etc)and it works great. I've also taken many deer with one. The bloodshot meat I have to trim off a deer shot with the 300 is excessive and unacceptable to me now days. I've come to the conclusion from field experience that a rifle such as the 9.3x62 (I have a 35Whelan improved which is very similar to the 9.3)with the larger slower bullets kill just as dead and don't do nearly the damage as the faster lighter bullets the larger 30 cals do. As far as the Sako 75, I can't say, but I had an old Sako in 375 H&H that was a sweet rifle with the best trigger this side of the old model 70's.
