Lukas and i were out at the range yesturday.
let me give you the conditions first.
sun from behind
+- 24 deg C
two different scope two different rifles
both Lukas and i noticed a difference in the ranging of the target distances, we first notices a 3m difference at 35m both ranged at 38m. we did not take much notice but when we looked at our 42m target and ranged 46m we were both puzzeled. what was wrong now? so we decided to try range again and again and again with the same results, 4m to long. eish what now? ok dial 48 and shoot knowing it is 4m out and yes shooting to high. now dial 42 and shoot well it was spot on.
ok now what will happen at 50m 5-8m out and there is no way you will hit.
then the sun went behind a cloud and gues what rang was now 1m out and not 4m??????? then the sun came out again and gues what back to 4m out. so we decided to test 10m, 17m, 23m, 28m, 33m, 35m, 39m and gues what only from 33m was there a difference (HWY????) but the difference got bigger the futhure out we went. 1m out and 33m 2m out at 35m 3m out at 39m and 4m out at 42m.
so what do we do now? the only conclution that i have is try remember that on a clear day when the sun is bright and from behind you might be over ranging!!!!!!
then what would happen when the sun is in fron of you??? will you under range???
