The 270 WSM is an excellent caliber, but I will stick with my .270 Winchester for whitetail deer. I have used the 270 Win for 35 years, and have had only one deer ran more than 20 yards after impact, and that was due to poor shot selection when I was young and foolish. In my opinion, my recent use of Federal ammo with 110 g Barnes TSX bullets has brought my .270 up another notch: the ammo is very accurate, extremely fast (3400 fps at muzzle), flat-shooting (dead on at 200 yards when held one-inch high at 100 yards), and has excellent terminal performance (expands initially but maintains weight to exit the animal). I have shot seven deer since converting to the 110 g bullets, and five were flop-deads and two died within 20 yards. The ballistics of a 270 Win using a 110 g Barnes TSX bullet is similar to that of a 270 Weatherby.
In my original post, I neglected to mention that the recoil velocity of the 270 Win is less than that of the 270 WSM; it is generally acknowledged that increases in recoil may lead to flinching and a decease in accuracy.
I'm sorry that I hijacked this thread, but I love my 270 Win and would recommend it as life-time gun for hunters. Young hunters can use this caliber because of the availability of managed recoil ammo, and then later graduate to hotter rounds such as my favorite.
