Paul, did you make the outside diameter of the 1902 peep larger?  I can't see the 1902 peep.  I tried the notch but it was too hard to find the front sight during rapid fire.  I shot a 485 which wasn't good enough to place but there is room for improvement if I can get this sight thing figured out.  Gonna try the 1901 peep next. One of the guys in the club finished 2nd or 3rd at Perry last year with that configuration.  Shoots spitzer bullets too.  My first match with a Krag rifle and I was pleased with how balanced it is.  I shot a 95 offhand which was my personal best with any rifle.
