GOSHOOT,

I refer to the amount of brass headstamped by it's

manufacturer as either 470 NE or 500 NE 3" or 3 1/4".

More brass marked 470 NE is being produced than brass

marked 500 NE 3 1/4 by FAR! Perhaps the 500 NE 3" PLUS the

500 NE 3 1/4" brass being produced today is HALF in number

compared to that being produced with 470 NE markings, [my

estimate, hence my comments]. FEDERAL AMMUNITION choosing

to produce the 470 NE 3 1/4 " brass impacted on EVERYTHING!
I don't follow the logic of your statement.
