I have shot the XP3 in 30.06 150 gr and 300 wsm 180 gr, the last 2 seasons and have loved what they have done. The first was my .06 at a muley in Colorado, hit him a little far back at 315 yards but still got some lung and he only went 20 yards and fell over dead. The second was in 07 with my 300wsm in Idaho, put another muley down at 501 yards (Leupold vx-111 scope with B&C reticle) hit him just below the backbone at over 500 yards and the damage was amazing for that distance. Does cause a lot of blood shot, but I would rather cut out a little chewed up meat and put the animal right down than have to track him very far. About the only thing I dont like is the price!($48.99 for the 300 wsm)
