Re: .223 Hand vs Metered Charge
Shooting over MOA targets? Why bother trying to load for accuracy if your target can't tell you how you are shooting?
close ranges like 600 you can get away with a lot unless you are really looking at small group sizes.
You will not get away with it at longer ranges.
Load windows are great up to a certain range. After that you need to be as close to your accuracy load as possible.
It goes back to "accuracy". If you are happy with large targets and not pushing your limits (Plinking) then I am sure you can forget about taking a great deal of care with loads.

In small cases like the .223 you WILL get large variations with sloppy loading. Large cartridges tend to be more forgiving.
You cannot get better, you cannot learn without accuracy. Your equipment must be more accurate than you.
Anyone take down a box of FGM and weigh the charges? Anyone have access to the bulk powders they use?
