Starters for 10:
Reparallaxed Bushy 6500 4.5-30x50: short enough, v. clear optics but a bit of a bugger to learn in terms of rangefinding.
You may get away with a Bushy 8-32x40 with high enough mounts, but getting owners to part with them is a bit of a "cold dead fingers" situation (I have 2 - nope!)
Take a look at the high mag Athlon range as well. Try Opticswarehouse.
