poi vs poa ar 10-308 zero techniques

[TxVet33]

I recently zeroed my AR's for a 50 yard zero using a 10 zero target/range.
Is there a target someone has used to zero a AR10-308 for a 100 yard zero at 10 yard range?
Asking for a friend. ")

Here is YouTube video I watched and used. It works for me.

Shooting it at 100 yards is the only way to be accurate, and it isn't that hard to do. Zeroing at 10 yards just helps make sure you're hitting paper at 100 yards. There are so many variables to consider that I wouldn't trust a 10 yard target to tell me much about what is going to happen at 100 yards, or even 50 yards. You could have 200 fps or more difference between 2 brands of ammo, over 100 fps difference with the same ammo from different guns with the same length barrels. And that is before we consider different bullet weights and barrel lengths. Plus tiny aiming errors that don't show up at 10 yards will be magnified by 10X at 100 yards. If you're off at 10 yards by one bullet diameter you'll be off about 3" at 100 yards.

Once zeroed at 100 yards you're going to be accurate enough to make pretty accurate predictions for where you'll be hitting at longer ranges. But you still need to verify by actually shooting at those ranges.
