They are both ATA 3dr max handicap loads.

I still have nine boxes of the AA's left in a flat that I won at a shoot in Fresno about 15 yrs ago. Maybe someday I'll use them for pigeons since I will most certainly never use them for ATA.

Even the GM 3 1/4 - 1 1/4 factory pigeon loads are easier than the AA's.

I'm sure it has nothing to do with burn rates tho.

over and out
