AR chambering method while load development

[cory]

I backwards feed the mag, so that load #5 in a string goes in first, then #4...until my first load to be shot is at the top of the mag. No single-loading for me...

+1 to this. I have horrible handwriting so the writing on the case doesn't work for me. haha

There's not really a right and wrong as I've seen it. Consistency in all aspects of reloading is much more important. Find a method that works for you and do it that exact way every time, whether it be throwing a charge, loading your ammo into the case, etc.....
