I bought my first .270Win. in 1968, owned about a dozen since, all P-64-70s, except one FN-Husqy and one Husqy 4100. I currently have three P-64 Fwts, all in top end synthetics, in .270 and I load 150NPs for hunting exclusively.
It was for many years, my second favourite cartridge, after the superb .338WM and I still love it. However, I started monkeying with custom .280Rems. in 1981 and last year bought a .280AI in the Kimber MA, for some reason, I seem to prefer the .280s.
I have fine, custom 7x57s and a 7-08 and find all of these with good bullets about "ideal" for BC hunting as the rifles are light enough to carry in steep country and 150/160 NPts. seem to kill well.
Actually, unless one frequently practices with heavier rounds such as the .338 or 9.3s or .375s, all of which I own several examples of, I think that one is better off with a .270-150NPt. or the other rounds listed above as they are MUCH easier to shoot well on game.
At 6 weeks short of 70, with the next season being my 52nd. and decades of mountain work and recreation behind me, I can say that a LIGHTER rifle IS better and if you can't "do it" with a 7mm-150/160NPt, you probably wont with a bigger hammer.
There, IS some advantage to the .338WM, etc, but, ONLY when you can really shoot it and in some circumstances.
YMMV-JMHO.
