Home Forums Hunting & Shooting AR and Tactical Rifles 24HC Black Rifle Challenge Thread

So in the interest of discussion, here is a target that I used for zero confirm with the same gun/ammo and model of scope. Four different 5 round groups spread over one month. The end result is that the overall group size for all rounds is about the same as one average 10 round group. I have done this a bunch of times and it's always the same whether it's a bunch of 1 shot "groups" on the same target, a bunch of 3 shots "groups" on the same target, or a bunch of 5 shot "groups" on the same target. The reason for this is simple- statistical relevancy.

It isn't the size of those three or five shots groups that's the issue (it is... but), it's the fact that those three and five shot groups don't land in the same place every time. The whole purpose of " grouping" is to know the size of the cone to allow one to know how accurate that rifle is (hitting targets).


In any case..

1st five (looks zeroed, right?)-





2nd five (notice how the group isn't looking so centered anymore...)-



3rd five (again notice center)-






Last five (





That target compared to the 2x 10 round groups from today.




There is 1/10th of an inch difference between them and it's in the 10 rounds groups favor.




The gun doesn't know whether it's firing it's 1st round, 3rd round, 5th round, or 50th. If a gun is a "sub MOA" gun, then that means that of a sub MOA target is hung not one single round will miss it.
