from my experience At 200yds=scopes- you will need to shim the mount or go to something like burris rings or a pitkittny?? mount- iron sights like the kimber/anschutz will run out of elevation and will need riser blocks or altering the ft sight the older redfields (olympic-international-palma) are ok- some people like to keep the scope in its elevation middle range as they feel that this is where the optimum performance opticly is
