Have a new-to-me fixed sight wheelgun (S&W M10-5) that groups like a match revolver but consistently prints 1-2” left of Point of Aim at 22 yards. Been experimenting with different bullets and loads without success, though much to my surprise, a taper crimp on my favored bullet (Lyman 358432) moves the groups closer to POA than what I achieve with rolled crimps.
Choice of powder does not seem to affect the situation, though I’ve tried only one or two in addition to Bullseye. The three or four bullets I’ve tried so far all shoot to left of the sights.
Problem might be the gun, but it could also be my grip, trigger finger position, shooting stance, choice of lube, seating depth, etc etc. I see no sense in sending the piece off to Smith until I have exhausted simpler and more obvious options, or proven beyond doubt that the problem is with the gun and not me.
Any thoughts on how I might coax groups closer to where I hold - windage-wise? I can live with variance in elevation.
This is my first serious experimentation with a fixed-sight revolver. Maybe I’m expecting too much.
Look forward to your input. Thanks
