Great post as normal. Speaking of trajectory shifts and environmental factors, I'm very curious to see if and how much change there is for me at the new location. My previous altitude was definitely thinner air, and we could tell when cooking, etc. We were previously in Colorado at about 5,800-6,000 ft. elevation above sea level, now we are "down" in the hills of Vermont at only 660 ft altitude. There is a HUGE difference in humidity as well. I'll be very interested to see if my rifles are at the same zero, (I'm sure it's shifted a bit), and interested to see how much it changed. I haven't found a long distance range to shoot at yet here, only the 150 yards on the property. If I had to take a wild guess, I'd have to project that it's less than an inch difference at that distance, probably more like a quarter to half inch or less. But as many people have said before, "Let's experiment"!
I just ordered some target hangers today, they are fairly inexpensive portable models that come in a DYI kit and use some inexpensive electrical conduit for legs. I've heard some good things about this kit from others. I'll do a post on those once they arrive. https://www.yankeethunder.com/
