| My question is ....... say I have a scope and i zero it at 100yds how do you record that for a data log ie. the dials are pretty much infinate on how much you can turn in either direction. Do you just mark you natural zero and record adjustment at diffrent ranges and wind conditions??? Also how would you do the same with a eotech or aimpoint? And do you adjust your dials at futher distances with a red dot type or do you just leave your bzo and learn you holds??? I did a search but couldnt find answers any help or links would be awesome Im asking this because i would like to record shot data and round data just to learn more about how my rifles perform under diff conditions. I apologize if im not clear enough im posting from my phone.any links /help is appric |

If so, you'll have to make your own scale markings for your adjusting screws. I don't know how you'll accomplish that to give you the accuracy you may want. If your scope has the click type of adjusting screws, you do finalize your zero at one distance, then reset the adjusting screw scales to '0.' From there you record your environmental conditions as well as where each shot impacted your target and what adjustment you used. Try to resist the temptation of shooting very fast as you'll heat up the barrel. Temperature change of the barrel affects where the bullet lands. As for data logging when using any type of reflexive sight, you'll have to figure out something there with making your own markings again. The reflexive sights are more about speed in getting the aiming point onto a target as opposed to "taking your time in lining up your shot." In any event, every shooter should be familiar with his holds (within reason) no matter what type of sight he is using. Hope this helps. |

They click. And I think I had the right idea for the scope.... Say like right now my scope dial has a I""""I""""" O ''''''I""""I""" type marking and it zeroed at 100 yds elevation is 10 clicks up from zero and windage is 3 right. you are saying record that as my 100yd zero and knda go from there. so for 200 start at closest zero on dial and count clicks until on target. it dosent really matter that the dial is infinate Im just getting a base to start from. Correct? And I was right in how I set my red dot
Thanks. |

At this point, reset your scale so that '0' matches the index mark on the adjusting screw housing. This is your 100 yard zero. so for 200 start at closest zero on dial and count clicks until on target. it dosent really matter that the dial is infinate Im just getting a base to start from. Correct? And I was right in how I set my red dot Thanks. From your 100 yard zero, log the number of clicks it takes to get a tight group at 200 yards. Some people call this the "comeups." Don't reset your adjusting screw scale at this point unless you want the 200 yard zero to be the base zero. Repeat the process for other yardages you are interested in. You can put everything on a small card for reference. |

typically once you zero at a given range, the turrets can be loosened and moved to back to zero without changing the internal zero.
then you would just need to count the clicks up or down to another range and record that number. then just turn the elevation back to zero and you're POI = POA at your original range. same thing for windage, if you are compensating for a 20MPH wind from the left, you make your adjustments. when you're done shooting, turn the windage back to zero and you'll be back on target for no wind. does that make sense? for a red dot sight, I zero for the flattest trajectory possible, for an AR15 that's 50yd/200m zero. some people prefer 100yd zeros. either way as you said, you just note your hold overs. with the 50yd zero, i can score COM shots out past 200m with no hold over and still easily break clays at 100yd. |
