Re: reset zero range after firing?
For the Long-range and extreme-long-range you must go back to your 100 yard zero because of all the varible yardages you may be shooting.
There may be a shot at 1000 yards then the next may be at 1500 and then back to 600 again depending on where the game shows up.
If your not used to firing at varible ranges, It is VERY easy to forget how many clicks were actually put on. Therefore it is best to go back to the 100 yard zero after the firing is done at one range so you are ready for the next.
