Well i loaded up some rounds with 180 sierras and went back to the range today.

At 42 grains Re15 the rifle grouped 2" for 5 shots at 50 yards with one flyer going high to pull the 6 shot group to 3"

I think that with more practice with the sights i could do better though bacuse the bead covered 6" at 50 yards and it was hard to get a consistent aiming point on the bull. each right-left string landed about an inch from each other though so it seems to regulate quite well.

Thanks for the help guys,
Brett
