I've used a Weaver V10 for nearly 20 years on a 300 Win. The view is different but you get used to it. I bought one of $119 close outs just to have. Use it before you decide. My wife loves hers on her 243, and my brother has put a few miles on one on a 270.
I've had one on a 243 for 16 years and like it fine. As you say, the view is a little different but it's clear, bright, holds zero year to year and the actual field of view is just as wide as the other scopes I own in it's power range. In other words, the so called "tunnel effect" amounts to doodly squat.
