If the OP has been shooting a .270 for fifty some odd years I'm not sure there is much difference in recoil for similar rifles, similar bullet weights, loaded to the same velocity chambered for 7x57, 7-08, .280, .270, or for that matter, .284. Yes, some will do it with a bit more or less powder (which will have a minor effect on recoil), some have the ability to go a bit faster (with a bit more recoil), and some might handle
Agreed, in Texas the .270 is still king, but in the 7mm class going with a light weight thin barreled or short barreled 7-08 could be lighter rig than a .270 without giving up very much power. A .280 will be as heavy as a .270. which would not leave any reason to change.
