Gents,
The .270 Winchester is a fine cartridge, but like Jim, I've never owned one. There's no reason you can't get 3,000 FPS from your featherweight. IF you handload. Interestingly, the velocity difference between a 22" and 26" barrel is about 100 FPS. MY own testing showed that the breaking point, ballistically, was at 23" inches. That is, of course, unless you are shooting something in the .338 Lapua class. Then the longer/larger powder train AND the longer barrel add velocity.
The velocity gain beyond 23" for standard cartridges is not that great. Consequently several of my custom rifles have 23" barrels. Somehow it just looks "right", too.
For me, my most used hunting cartridges are the .284 Winchester, .308 Winchester, and the .35 Whelan Ackley Improved.
For tactical use it's the 6.5 X .284 Norma, .308 Winch, and the .338 Lapua Mag.
Hope that helps.
