I'm currently having 2 long range rifles built and I'm looking for dependable optics. There are so many choices now, when I got my custom 7RM I put a MK4 4.5-14x40 on it and never thought twice but now there are alot of scopes in this price range. The 2 that have caught my attention are the Burris 6-24x50 XTR and the Sightron S3 6-24x50. Both have side focus, turrents, 30mm main tube, and the magnification range I'm looking for. I belive the Burris has 1MOA elavation and 1/2MOA windage adjustment. Sightron are 1/4MOA adjustments. Question are they dependable (do reticles break loose, repeatablity,etc)? How good is the glass in either one of these? Any thoughts are welcome as I'm really not leaning toward either one just doing some research.
