Jeremiah and I started out trying to shoot those rounds, but they will not shoot out of our Senderos. At 300 yards, we were shooting about 12" groups. It was bad, and we were getting pissed off. The Accubonds are shooting great out of it though. Can't wait to really stretch it out.

Antlershed,

Did you read through that link?  One big thing that I picked up on that cut my group size in half was bullet runout.  This caliber is very picky when it comes to runout.

Out of the box, my guns loved the scirrocos. 4" group at 300 yards across the hood of my truck aint so bad...for me... I can keep a pop can moving at that range......
