Years ago my late father-in-law killed a good bull elk with one shot with his M99 .300 savage . He couldn't tell me exactly what load except it was a 180 gr. factory load. He kept Win. and Rem. round nose and spitzers mixed in boxes and in the magazine. He said they all seemed to shot the same so he didn't keep track of what he was using at any given time. It kind of disilllusioned me about precisely loading the perfect load with the perfect bullet for hunting.
Some people see the .300 Savage as a lower powered .308, I see it more as a super .30-30; either way makes it a good game killer especially in those slick handling old 99's.
