Just now saw this post.
.270's a great caliber. If you're looking to spend some money for a noticeable gain, go with a 300 mag minimum. Super versatile caliber. If you're looking for an elk cartridge, buy a .338 Win Mag. You'll not regret it. Between the 270 and a 338 WM, you've got everything covered.
As for recoil, not much difference between the 7mg, 300 mag and the 338 mag. All are substantial so if you're going to tolerate it and practice with it enough to get used to it, might as well push a heavy bullet with authority - .338 Winchester Magnum. I hunt deer with my 270 and 3006 but elk with my 338 with confidence no matter the shot angle.
Also, no matter what you shoot, use super premium bullets.
