Thanks for all of the replies. This makes me feel a lot better about it. Maybe I just had a bum bullet for that shot.
I will start on the long, expensive process of trying to find a factory load that it likes. The best grouping I had was with the 130 BT and that was 2-1/4" @100 yards. I get better groups with my ML! [&:] But, as I said, there are a lot more loads available for it now.
