thanks for that info.  I just tried it out, at 50 yds, with a tiny old weaver 4x fixed scope.  I guess the guys who put this baby together, really knew what they were doing as far as squaring up the receiver bridge for the ring mounts, then trueing up a bbl.  I put the scope in, and shot at the dirt burm behind the 50 yd line, aiming at a depression in the dirt.  Wham!!!  first shot is dead on windage, and maybe 6 clicks low, adjust and fire two more times.  Dead on!! So now I go for paper, and it is pumping a large hole in one spot on the paper, but it is diff to see with such a small power scope, the center of the target lines on the paper.  
  So since i cant disect lines within the targets, I put up 20 1 inch dots, all shoot n see spots.  I take 20 trigger pulls, 20 dots, 30 seconds between shots.  Twenty dots hit, bleeding their yellow juice, baby!!! So nice, when you get a precision rifle, it is hard to go back to regular factory stuff!!! Oh well.  This was done with standard remmy 100 grain power points.
