Well,
I had some Sierra 50 grain varminter SPTs in the cabinet, so I gave them a shot with 25.0 grains of IMR 4895 and CCI 400 primers. I had it dialed in good at 25 yards, and was hitting a barrel at about 520 the other day.
The wind was blowing too bad yesterday to shoot a group at 100 yards, but I will try that soon.
I will try not to move the sights much, as this is my duty gun also, and I need to make sure it is sighted in to that ammo (which doesn't shoot worth a crap anyway, thats another story).
I am pretty pumped about loading for this gun now!
Later,
Marcial
