Colorado, I just talked to my friend inquiring what his loads were. He is at work and will let me know. He did say that the 400+ (not sure ) regulated very well and grouped around 2-1/2" at 100 yds each barre, did not cross. He is still working up the 500 gr. load, that one is not quite there yet, that one is 2" at 50 yds I believe. I have shot this one and it is very stout indeed.

The gun was originaly regulated for I believe he said 87 yds, but don't quote me on that.
