I am attempting to develop a hunting load for my Savage 10 FCM Scout (7.62x39). I am planning to hunt with the factory ghost ring sights. For anyone with ghost ring sight experience, what kind of accuracy should I experience without using glass?

Background: I understand cheek weld, sight picture, etc... I have shot DCM/high power competitions with open sighted AR15 and M-14 rifles, so I ( ::)think I) understand the fundamentals.

I am currently breaking in the barrel and trying to develop a good hunting load. I attempted a ladder test today and got about a 5-6" group (27 rounds). Minute of deer? Yes. However, I am wondering if it is even worth it to try to develop a pet load as I would with a scoped rifle.

Your thoughts would be appreciated, especially if you have used a ghost ring sight-equipped rifle.
