Reading the wind is on the shooter not the round and certainly not the die. As I said a sub moa load at 100 yards with tight velocity numbers and appropriate bullet choice will be sub moa at 500 given the shooters abilities. Micrometer seating dies have dials for easy adjustments in seating depths which is nice when you shoot multiple bullets in the same caliber or doing seating depth tests in load development. I have whidden, redding, rcbs, and lee dies. They are all capable of producing match winning ammo based on my real world results.
Yeah I never said the wind was on the die? I just simply said that variations in the rounds are a lot more pronounced the farther from the target you are. Yeah I have loaded quite a few rounds myself that go in one hole at 100 yards but at 500 not so much.
