Hey, sweet pics. Looks like youre a lefty, that officially makes you evil - just kidding. BZO that bad boy from 10m from as stable a position as possible. 10m is ballistically the same as 300m on these rifles, thats why in the USMC we BZO at 10m before quallifying on range at 200, 300 and 500 meters. Obviously its alot easier to see what your rounds are doing at 10. Before you BZO get your front sight tip flush and get your rear sight set for 300 (what you set it at depends on your sighting system). You could get a mechanical zero with a laser boresight and all that fancy stuff but it still wont be the same as YOUR PERSONAL BZO. Everyones BZO will be different even with the same rifle. Once youve got that weapon BZOd leave that FST alone and adjust all your dope off the back end. If your groups are wide open dont do any adjustments until youre getting solid groups, then adjust to get that group where you want it. Dont adjust where youre aiming, keep sighting in on the center of your target and leave that kentucky windage for the hatfields and mccoys. Aim to center and adjust your group to your aim. Take your time and maintain your fundamentals - especially focussing on your front sight tip. Clear FST, blurry target.
