My figures come up to about 675,360 pieces of 5.56 brass,if that is net weight.
(This is a guestimate based on a lot of half a figuring using some Aguila fied cases that may not be as heavy as USGI brass)
If the weight figure includes the crates (probably) I would guess still over 600k of brass.
My F250 will handle the weight,but might not handle the bulk (I don't know how many crates there are,and I'm not hauling them loose in the bed!).
A tandem axle trailer (with brakes if you want to stop it)will probably haul all of it behind a full size truck.
As high as scrap prices are right now,I expect the bidding to be spirited.
I think high grade copper is bringing about 2 bucks a pound(someone told me the prices tonight,but I didn't pay attention since I only have aluminum, cast iron, and steel scrap).
Brass is probably near 1.50,but I would have to check that dollar amount.
At a buck a pound,scrap value would be about 8k.
Does that jibe with your numbers ATLGA?
Edited to correct my math(used a calculator this time!).
I'll keep an eye on it,and see what happens!
Maybe there will be a for sale ad in the EE for brass soon!
