So I got to the range a couple of days ago to compare the ballistic tip ammo for the following:

Winchester supreme Silver ballistic tip. 150 gr
Federal premium nosler tip. 180 gr
Hornady Outfitter. 180 gr

The federal and the hornady grouped similarly with POI in similar location to POA....roughly 2" high, 1.5" right, groups 1-1.7"

Started shooting the 150 gr WSSB...and wasn't able to hit a 9" diameter plate.....it wasnt until I set up 2 plates in a snowman configuration before I could realize the 150 gr WSSB shot 8.5" higher than the 180 gr offerings, the result was a 3shot 1.5" group.......that seems a bit strange to me.
