FINALLY remembered to carry the Speed-Six to the range (it is the bedside gun) and the results are... (drum roll please)... 1359 fps avg for 648 fpe with an AD of 39 fps and an SD of 51.

I have to say that I have one chamber than consistently gives lower velocities and one that consistently gives higher velocities with every load.

Also, I shot for group at 25 yards. I got 3 and 3½ inch groups for 6 rounds. This is a romper stomper compared to most loads I've been using. When I want something really powerful in a handgun I go to a .4something! Again, the 180 gr. bullet load gave 1179 fps for 556 fpe from this gun. I did shoot it for groups too, but at 50 yards and it gave 4-6" groups at that range.

The 180 gr. Rem SJHP load went into a 1.75" group at 100 today. I think this is remarkable given the sights (particularly the front bead). Another interesting point is that zeroed, the Williams Foolproof is resting on top of the receiver! One would truly need a higher front sight with this gun and an aperture sight when using lighter bullets. I've never needed to replace the front sight on any other levergun after mounting an aperture sight. This gun might be the exception. If so, it will get a sourdough front just .002-.003" taller. I think that is all the extra front sight it would need to zero that barn burning 158 gr. XTP load that goes over 2000 fps.
