Stop your search and just order the SHV
This. ^^^^^^
I bought one to try on my Kimber Montana 308. I quickly ordered a second.
The only down side is weight. They will weigh 21 oz give or take. Compared to a Leupy, they seem like anchors. But rock solid performance is the trade off. You dial 2-10-50 'clicks' (MOA) and it moves 2-10-50 units. I banged mine around on 2 elk hunts and several weeks of deer hunting last year. Zero hasn't changed.
