UPDATE, UPDATE! Installed the new front sight, (which I trimmed down about 1/10"+) and went back to the range. Drifted the rear sight slightly left of center (about 1/32"), and dialed it in. Dead nuts on! POI is about 1.5" above POA at 25 yards. I then took out clay pigeons on the 25 yard berm, and even a clay pigeon on the 100 yard berm. Nice shooter.
Shot my 7.0 grain Trail Boss hand loads (200 grain Bear Creek moly coated bullet), some Black Hills and HSM .44-40 factory. Black Hills gave me 1 1/2" group at 25 yards, where HSM factory gave me slightly better at 1 1/4".
My trail Boss loads gave me 1 3/4" groups, but that is expected, as the maximum charges of Trail Boss are not as accurate. I did six shots rapid fire from a rest at a 2.5" group.
All in all, it was a great day. I'm glad my wife insisted I pay for it now and keep it, and not wait until the 6 month trial is up. It will alternate with my HRA 1860 Henry .44-40 as a main match rifle.
