Bob_S,

Thank you SO much for walking me through the pros and cons of both sights.  At this point, all I have available to me is a 100 yard range so I'm not going to be duplicating the 2000 fps military loads in my shooting.  I've heard rumors of a private 300 yard range in the area, but as yet haven't met anyone who knows more than 'a buddy of mine knows of someone who......'. 

I'm located between two nice 1000 yard military ranges but they have pretty much locked down outside use of them, even by retired personnel.  I would once however, like to take them, and other rifles obtained since the closure of the ranges, out to try out their legs.  I scrounged up 3 boxes of commercial ammo for them and a 50 piece bag of brass.  I'm thinking that if I get another 50 piece bag that will give me 80 rounds apiece for them and that should last me a long time-particularly if I'm shooting light loads.  I'll neck size them only to specific rifles like I do the .303 and I should be good for 8-10 uses each or more depending.  That may sound like a lot for just a 'toy' but I've had the dubious experience of running out of ammunition in a firefight a couple of times so I am always somewhat of a 'hoarder' when it comes to ammunition.

Again, I need to say thanks for your explanation of the sight.  But I do have one more question.  You mentioned that the 1902 sight elevation slide was clamped similar to the 1901 sight so does that mean I can use my O'Hare device with it if I want to get real serious about shooting long distance with the 1902 sight?
