| I am going be zeroing a sniper scope on a Springfield M1A. I was wondering if when I zero the weapon to the scope at 200 yards, would the weather conditions of the day that the scope is zeroed-in have to be taken in consideration on a ballistics chart in relationship to the new barometric pressure and humidity on day of competition even though these may be a week or two apart. I guess what I'm asking is that after the scope is zeroed, this then becomes the benchmark, zero clicks, for further competition. So, when I use a software ballistics chart, to create a new ballistics chart for the day of the shoot, are there any considerations that need to be taken for the differences from the original zeroed day to the actual competition day. Thanks in advance for your response.[/size=1] |

Some of the guys over on the precision rifle section could answer you better, but yes, technically the atmospheric conditions can have an effect....especially at longer ranges.
also, friendly warning, the term "sniper scope" is gonna get you burned |
| Your zero is good only at the moment you create it essentially. As day the changes, you'll need to adjust with it. (Learned this the hard way when I first started competing. My great day turned to crap 1.5 hours later as the Sun changed its position in the sky and the temp, wind, air density and lighting changed on the ground. Live and learn!) |
