Initial testing of the 7prc today was .5 moa @ 1000 yards. Not bad but no improvement over my 7 wsm. Actually 7wsm is about 20 fps faster then the 7 prc. But because of factory loads from hornady I see it doing well. I do believe it has a average stability factor at 8 twist. As ive seen from the 1000 yard groups at 30 inHg, But I will re twist it and test it before we start production,
