Glad to hear you are having good luck with the Shepherd scopes.I liked their concept.I truly hope our troops have as good luck with them as you have. My luck has not been so good.I have one that I am selling.
I like their scopes. The only problem I ran into was that the bullet needs to be almost tailored to the drop of the scope, instead of the other way around. I have one on my .308 for medium range <600 yds and like it. It makes it REALLY easy to range with the reticles. I went head to head with a mil-dot and we both had about the same deviation from actual, but the shepherd was MUCH faster to range. Just my $.02....
I have the P2 I believe. It is the one for a 300 win mag. Anyway I could not get it to hold a zero. I thought I had it corrected and when I took it on a Elk hunt I again was not able to get it to hold its setting. the cross hairs would not move and then would jump a good distance. I love the scope's concept but I want a scope that I can trust. I personally am sorry I bought it. My luck with Leupold and others has been much better. This is my two cents
