Ping pong balls for the win. Once you've wrestled everything else in life is easy. Dan Gable I keep my circle small, I’d rather have 4 quarters than 100 pennies.
Thanks! Just really trying to confirm some data out past 1000

That tends to happen in switchy winds at a mile. Any up/down drafts to deal with? Coriolis enabled?

Nothing up or down that I could see. Good Catch! Coriolis is always enabled, but I didn't look at it or put in the azimuth of fire. I just did and it made no difference in drop? It should as I was shooting West to East and would explain the fact that I had to dial more than the original output...

Jordan, I'm actually a bit confused by this. Everything I've read says shooting West to East would involve less drop. Doesn't seem intuitive to me since, with the rotation of the Earth, the target would be getting FARTHER away. Can you help me noodle through this?

"Despite being associated with Coriolis, the phenomenon that actually affects the vertical component of the trajectory is called Eötvös Effect. The rotation of the Earth generates a centrifugal force, the same that pushes you to the side when you make a sharp turn with your car. This force acts perpendicular to the Earth rotatory axis, adding or subtracting to the gravity force. When an object flies eastward, in the same direction of Earth’s rotation, centrifugal force acts opposite of gravity, pushing it away from the Earth’s surface. If the object flies westward, in the opposite direction of the Earth rotation, centrifugal force pushes the object toward the ground concurrently to gravity force. Thus, bullets fired to the east always fly a little higher, and, conversely, bullets fired to the west always travel somewhat low."
Seems opposite of what I'd think

Rather than thinking about the target travelling further away with the rotation of the earth, think of the target rising or dropping with the earth. The earth rotates from west to east, so if you were shooting towards the east, the target would rotate and drop down a little bit while the bullet is in flight, and the bullet would then strike higher on the target. So you need to dial a little less elevation to bring POI down to POA.
If shooting to the west, the target would rise while the bullet was in flight, and the bullet would strike low on the target. You would be required to dial a little bit extra elevation to bring POI up to POA.
I am in over my head every time I try stretch my rifles out much past 650. Have tried it at various temps and altitudes, in hunting scenarios across canyons and such, and haven't gotten a handle on what happens. I salute you guys who've figured it out, and are putting rounds where you want them way out there.

In terms of clanking steel, I felt the same way but once I started pushing my comfort level and going through primers, the learning curve was surprisingly steep and quick. I'm still all to familiar with misses but feel I can get on the plate in short order with the tools we have these days...not to mention some of the people here who have refined the skill and divulged their experiences.
I think it was Tubb that said that once you got to magnum speeds in the 7mm that strange things happened at times at longer distances.
Nice shooting!
Only time I've done that, was a bit furhter but with a 50. Amazing how you can think you have it all swag'd out and you miss by quite a bit, but given a spotter you can often do well for a few more shots, but then looks totally the same and you miss again.... best outing was 3 shots around 8 inches at a bit of 1800 ish yards... pretty much a fluke IMHO but i"ll take it. I decided that I could hit or scare the heck out of a 55 gallon drum there most of the time anyway. TOF was about 5 seconds IIRC...
We can keep Larry Root and all his idiotic blabber and user names on here, but we can't get Ralph back..... Whiskey Tango Foxtrot, over....
I saw that video and thought I understood what was happening. This site says the reason is centrifugal force caused by the direction the Earth is rotating
