.08 mils is 1/4 moa at 1000 yards. I have no problem adjusting for that.
You're so ignorant you don't even know what you are looking at. This why people say the internet is dangerous. Just enough information to be completely wrong.
Frank, I am perfectly capable of doing the math. I am asking you the question so you explain your belief and understanding better and educate me considering you feel I am the one who has the problem. I don't have a problem with you correcting something that I believe is true, that is the point of the forum correct? as Graham says, to discover the truth?
If it is not too much to ask, how about backing off just a little from calling me ignorant, if I was ignorant I would not be asking you to clarify or correct things you have said or things I have said so I can gain a better understanding of them. You are the one that knows the information, I do hope you are willing to share it. Rather than turn it into a session of name calling, is it too much to ask for you to explain to us/me why all these people that believe in CE are wrong or at least why it should not be considered. That way we OR I don't continue to spread misinformation and perpetuate the "myth" further.
I am interested in hearing what you have to say on the matter from your experience standpoint, I find it to me one of the most credible in the forum. I am more apt to believe it and take it to heart when I am not being called ignorant in the discussion.
In the terms of absolute, I consider 1/4 of an MOA to be significant at 1000 yards because 1/4 moa from CE plus 1/4 MOA from a bad wind calc, and 1/4 MOA from a bad BP reading added to another 1/4 MOA caused by a bad humidity reading added to 1/4 MOA for a bad altitude reading... the sum of all the errors equals a miss. If I can correct even one of those factors, that could be the difference of hitting the target and not hitting the target if I get everything else wrong.
You consider 2.68 +- inches to be insignificant at 1000 yards, in the terms of everything else being correct, it most likely is, but as a LR or ELR shooter, don't we have to consider all the variables in our calculations so we can minimize the effect of as many errors as possible?
When I originally said that you never can have a true zero at 1000 yards because of CE and the effect CE has in different directions, what I implied was the CE variations experienced from an absolute zero shooting in one direction. If there are no variations from zero at 1000 yards caused by CE when you shoot at a different azimuth than I am willing to accept that. My argument here is there is, based on what I have previously learned, regardless of how significant or insignificant they may be.
This is what I originally said:
Coriolis effect starts to screw with you at long range so you will never have a consistent zero at long yardages.
Then I said this:
Do a bit of research and you will find it is very real. Your better ballistic calculators calculate for this. Shooter for the iphone is one that considers this in its calculations.
I never said a single word about any distance. Then I referenced the video.
Then I said this:
6 inch difference east to west at 1000 yards is pretty substantial in my opinion. If your vertical dope is calculated shooting east and you use that same dope to shoot west, it is the difference between a hit and a miss on a 10" target. Same shooting north to south only the effects are horizontal. 1000 yard zero shooting north will be 6 inches off shooting (1000 yards) south.
And that is when I stepped in the shit because I made a statement that in effect said if you shoot 1000 yards in one direction, then 1000 yards in the other, the CE effect would be the same as shooting 2000 yards. A 6 inch difference. If you correct your dope for that 2.68 inches of rise or drop, turn around and shoot the other way, you will have twice that amount of difference because you calculated it at the mid point. If you left your zero at zero, you would have 2.68 inches low on one target and 2.68 inches hi on the other. The diference in the spread would be more than 5 inches. I rounded it to 6 because the belief, depending on your location in most places in the US, is 2.5 to 3 inches in 1000 yards.
the myth is you can or have too adjust for CE inside 1000m, I never bother with it, but you can after 1500m if you feel the need.
So am I wrong in assuming you are saying there is a difference past 1500 M that may be worth calculating for? Can you tell me what you believe the correct CE adjustment for 2000 yards would be if I was shooting east?
