Leupold LRT 8-25x50 sidefocus Burris BD 8-32x50 sidefocus IOR Valdada 6-24x50 sidefocus All have target knobs, price ranges are +/- $100 from each other, sometimes a $200 or $300 difference depending on the supplier. None of them have lighted reticle, that belongs to a choice I already eliminated..a $500 to $600 Nightforce feature. The IOR has 1/4 clicks, the Burris has 1/8", Leupold has 1/4". All choices have 30mm tubes, and if I wanted a lower power I could get a steel tubed IOR. I really like the ranging reticle of the NP-R2 and the IOR MP-8 so that is why I am in a bind... (maybe the IOR is more durable than the Leupy and Burris?) I have a 15MOA base and will probly grab a set of Signature rings or just spring for some Barrett rings. Rifle is a .338 Lapua with a 26" barrel, probly going to be fed with 250g Scenars for awhile. Intentions are to start shooting at 600 yards and beyond. I am leaning more towards the IOR since it has the Ranging reticle but I am open to other choices.
