I've got a B&L Elite 3000 on my 300 Win Mag. I've had the scope bounce off my shooting glasses a number of times at the range. It's got a soft rubber ring but I know if I'm not careful it'll be ugly! I would appreciate (and will spend some cash on) that extra inch of relief.

It happens to the best of us. Even a properly set up scope can induce "magnum eyebrow" after an awkwardly positioned field shot. Just gotta be careful.
