| Just now getting into longer range shooting. Anyone know links to a sight that could help me understand how to read the different reticles. MOA, Mil Dot, how to read them and make adjustments. my only experience so far is a duplex reticle. I understand bullet drop just dont know how to read that on the reticles. anything helps thanks. |

My best advice to you is to study external ballistics. Once you have a basic grasp on that, figure out your load data ( muzzle velocity, bullet weight and ballistic coefficient) and put in your general environmental conditions into the "trajectory" calculator at www.jbmballistics.com. Tell the program to make your elevation and windage dope in either mils or MOA depending on what you use. Now say for example you're using nightforce's NPR1 reticle which has 1moa hash marks, and the dope sheet from jbm says that at 500yd your bullet drops 12moa, you go down 12 hash marks from your zero (center crosshairs ) and that is where you need to aim to hit at 500yd. Obviously a calculation will get you close, but not perfect usually so you need to reconfirm all of your dope data on the range. I also suggest checking out nightforce optics and browse their reticles, most of them have decent descriptions. Just try not to mix mils and MOA. 1 mil is 3.6"@100yd, 7.2"@200yd etc... 1moa is 1.047"@100yd, 2.094"@200yd etc... linear angular measurements. 1 mil is 1 unit sideways every 1000 units away ( doesn't matter what units, metric or imperial). MOA is 1/60th of 1 degree. Now as far as using them to range objects, there are various formulas online... I personally wouldn't shoot at anything I ranged with a reticle unless I know the targets exact dimensions. All of that said, the hash mark reticles I think are most useful for follow up shots. I adjust for the first round using the turrets, then if the first shot is a miss, I use the reticle like a grid. So I aim at the target, then relate where the shot actually hit, then drag that imaginary point over to the target and fire shot #2. |
