You might also gain some relief with offset rings, like these.
Another thought- have you considered moving the scope back a little and/or shortening the stock, to get the scope closer to your eye?That Bushnell 4200 is a tough scope to beat in your 3-4 hundred dollar budget.
If you want the best eye relief, go with Leupold. A VX-2 in 3-9x40 is a lot of scope for the money. Probably won't be any better than your 4200 though, except in the eye relief.
I've been using the Bushnell Elite 4200 on my Tika T3 .270 WIN since both were new and both are my first. Love the rifle and scope is clear however with a few layers on the eye relief is just not enough for me. This year I want to upgrade, nothing fancy. 3x9 or 4x12 would work for me, a BDC reticle, multi-coated lenses and better eye relief 4"+ and decent warranty. Budget is $300-$400 or soI've been looking at a Redfield scope (link), but I'm not sold on it yet.And a friend swears by Vortex scopes that I've yet to check out. Any suggestions would be appreciated.
