FWIW, At 200 yards and shooting the standard load of 220 gr RN over 40.0 grains of 4350, my elevation is set at the 225 point on my 1902 sight.  Now whether this has to do with my use of the (modified) Sgt. Peep or not remains to be seen... but it does ok.  I also use a little "Kentucky Windage" in my shooting - in that I get it as close as possible, and then if I'm not deadnutz center, I adjust my sight picture to compensate.  It's just easier for me than fooling around with the sight adjustment during a match.  This may affect my ability to medal... but at least I'm not frustrated WHILE I'm shooting (I just save the frustration for after when I see my score, LOL).
