Optics calibration distance
@ 08:56 pm (GMT) |
Mike DeweyGot a Sightron SIII FFP 6-24x50 LRMOA on the way and planning ahead for calibration.What about calibrating it at 95.5 yards where 1 MOA = extremely close to 1 inch instead of 100 yards where it equals pretty close to 1.047 of an inch? Maybe easier and more accurate calibration... I shoot in a cow pasture so can easily move target distance. Also thinking about a range table with the usual distance intervals but with 'benchmark' distances added, that is multiples of 95.5 yards where the MOA adjustment would be more exact instead of approximate. What do you think? |

Warwick MarflittRe: Optics calibration distanceIt's only .047 of an inch 1.2 mm about the same size as a field mouses tail is thick at the tip! With a bit of wind and turbulence(like if the mouse farted) I don't think that it would matter ? As at 1000 yards it's 10 × 1.2 mm = 12 mm (the mouses head) do it if you want to cull mice at 1000 yards for sure. I'll buy you a beer and a pie if you nail Pinky and the Brain and these two annoying little Rodents

Mike DeweyRe: Optics calibration distanceThanks Warwick, always good to keep things in perspective. I wasn't talking about head shooting mice at 1000 yds though, rather checking the scope's elevation interval accuracy.If checking at a distance where 1 MOA = 1", 10 MOA elevation change should = 10" if all is accurate. Whereas if checked at 100 yds, 10 MOA elevation change would = close to 10.5" if all is accurate. Just thinking to make things easier. Like the mice though. |

Warwick MarflittRe: Optics calibration distanceHey Mike. You are right! Technically accuracy is and always will be about being accurate. Many guy's either just don't get it or can't be bothered making the effort or are too lazy to learn the skills. The kill zone area isn't just anywhere on your food of choice. Understanding the anatomy of animals and the size of the target zone to kill them cleanly and humanly needs to be taught to all hunters . Some of these guys and girls would be better off learning where the meat section at the local super market is! A wounded animal doesn't deserve to die a slow and painful death? My dad taught me that and compassion for your food don't make you soft or weak. I also don't like the longer carry back to the vehicle if Bambi runs away after being shot. If it's grazing and working to the top of the hill I'll sit and wait for it to get to the top and then carefully dispatch it.Like Grandad once said " Son To be old and wise. First you must be young and stupid " ? How many of you still get buck fever and forget everything because the excitement of the moment overtakes the need for a clear view of what is going to be done by you to another living thing? So if drop charts in 95.5 yard sections get you a dead mouse at 955 yards and gives you the confidence to shoot out that far then go for it! I think the reason for the 100 yard measure is because it's a standard measure that divides into itself as your add them together you always have an even number With the 95.5 y × 10 = 955 yds 45 yards short of a 1000 yards making the maths out long a bit more challenging ? As long as you know what you have and Mr Moose dies quickly then it's not a problem. Happy hunting everyone |

jasonRe: Optics calibration distanceIf it were me..I wouldn't bother it's a sightron no doubt it will be fine. Only run a test if I suspect a problem. |
