I just got back from the range. It has definite accuracy potential. At 25 yards it was almost a touching cluster. At 50 the mirage and disappearing front sight issue came into play. The bore is very, very smooth. I did not need to wipe hardly at all. I was using 60 gr 3F, 440 ball, 0.016 soapy patch.
I will make "old man" sights and do further load development. For my eyes I like a front sight that is about 0.110" wide and taller. The rear will be a slit. I set them up so they view like partridge pistol sights.
The issue sights are HC. The front was right down on the barrel to get it zeroed. They look good but are more suited to younger eyes.
