Not sure about the second part with the shots "climbing higher"? That could be due to a vertical component of the wind?
It sure could be, I haven't yet totally
proved to myself that horizontal wind causes vertical drift, but it seems to be a more recognized phenomenon here lately. I even started this thread a while back to try and get some answers.
Wind Direction changes our Vertical Impact......Fact or Myth?
In the video How to Dope the Wind Beyond Belief
, one guy talks about how the spinning bullet drops less with a right wind, and drops more with a left wind. Just as spin drift "rolls" the bullet right (RH twist), it supposedly also makes it drop less or more depending on the wind direction. He stated that for every 3 or 4 minutes of drift, there would be about 1 minute of elevation change.??
When I get my LRR all load picked and dialed in at 1000, I intend on testing this theory for good. I can shoot 1000 yds east and then turn right around and shoot 1000yds west in no wind conditions. Then on another day, when there is a slight wind from the north or south, I will shoot the same test at the same distances and try to see just how much the wind changes my vertical........problem is, on different days there will be a different pressure or temperature to deal with too. If Coriolis affects the vertical (like the program says) that's 6 inches vertical that would have to be accounted for. Might take a long time and alot of ammo before I can totally prove this theory right or wrong. Expensive too at $5 a crack and a new barrel after $1500 rounds.
In addition to the chart in the above link, here's another one that has been posted here on LRH lately. Even if it's never proved, it's interesting to discuss.
None of my programs address this phenomenon at all.
