It is just a boring truth that the 270 or any of the small 7mms will kill just about anything that needs killing. The only exception being really large and or dangerous critters.
But I just bought my first 6.5 Creedmoore and am having another 280 Ackley put together,and bought the 9.3x62 on your recommendation. And I had to have a 375H&H in case I have to shoot something really mean.
But my son hunts everything with the 30-06 I gave him and my daughter does the same with a 7mm-08,I just need the more exotic stuff to get the same things done.

It's a sickness.
