I remember reading an article by Col. Charles Askins, who took the then new 7mm Rem Mag to Alaska to shoot a Brown Bear. he used the factory 175CL. His comments, if I remember right, were "Why Remington chose the 175gr is a mystery to me as "everyone knows" that the 7mm Caliber is best "balanced" by the 160gr"! Admittedly, I've killed more game with the 150 and 175 than the 160. I can't see where the 160 NAB would NOT work, on about anything!
Seems to me the Col, was onto something.
I like 160's with the 7RM, 140's with the 7-08. Not that other combos won't work, those seem pretty well balanced.
I also like the 120 NBT over BG powder with the 7-08. Tough bullet, good accuracy, good velocity, effective at whacking WT's and hogs.
