I'm heading West to hunt ELK/Mule Deer for the first time in 10 years this fall, and I'm bringing my 300WSM. Currently, I have a Mark 4 6.5-20 Illuninated TMR on top, but I've never hunted with this scope - it came off of one of my target guns. Been thinking about selling it and buying one of the new Leupolds with CDS turrets or maybe a Nikon with a BDC reticle which are both intended more for hunting than the Mark 4. Thoughts?
