Ya thats what was getting me, the sierra 120s are perfect as well as the 117 hornadys tho there is a story behind the hornadys.
I also loaded some nosler 100 gr ballistic tips and 100gr hornadys with good results it was just the 120 partitions that gave me fits.
And the 12" groups were at 100 yds!!! (yikes!) No biggie tho I can live without the Partitions as long as they keep making the 120 Sierras.
I just thought it very strange.

Deer season starts next Saturday so I'm going with the Sierras. I'll play with it some more when I'm done hunting.

The 'Bob' is one fun caliber to shoot, don't know why I didn't get one sooner.
