I didn't shoot it even once with open sights Cayugad. I ordered the scope base the same day I bought the rifle and already had an extra ProDaimond in the closet.
I load 180 grain XTP's for it over 14.5 grains if Lil`Gun for a velocity of 1600 fps. It gives me groups right at one-inch at 50 yards and two inches at 100. Haven't shot .38's out of it, just .357 Mags. It shoots 158 grain bullets pretty well, but not as well as the 180's. Also tried some hot 125 grain loads I have for a handgun. They didn't do well at all.
