AGW - lots of good points there. I keep coming back to us wanting to achieve "target group accuracy" when our goal is "first-shot hunting accuracy", where all of those variables will have an effect on that one shot as well when compared to where it hit when the load was developed. I think that "good enough" is about all we can ask for.

Not a real member - just an ordinary guy who appreciates being able to hang around and say something once in awhile.
