How many 40 s&w brass will fit in bulkrate USPS box?:dunno:

It's not quite the answer you are looking for, but somebody PMd me this a while back...

9mm, 59.46gr/ea, 117.7cases/#, 8.5#/1000

38spl, 68.06gr/ea, 102.8cases/#, 9.7#/1000

40s&w, 70.1gr/ea, 99.9cases/#, 10#/1000

.357mag, 78.3gr/ea, 89.4cases/#, 11.2#/1000

.45acp, 89.58gr/ea, 78.1cases/#, 12.8#/1000

.223, 95.28gr/ea , 73.5cases/#, 13.6#/1000

.44mag, 114.38gr/ea, 61.2cases/#, 16.3#/1000

50bmg, 865.26gr/ea, 8.1cases/#, 123.5#/1000

All weights are uncleaned fired cases with the primer remaining.

Individual case weights were derived using an average of mixed brass weights (except 50bmg)

So, if you picked up 8#’s of 45 brass: 8# X 78.1cases/# = 625 cases+/-

If you use 1gal ziploc freezer bags to store your brass, each (full) bag contains:

9mm, 15.6#, 1836cases
40s&w, 12.2#, 1219cases
45acp, 11.4#, 890cases
223, 11#, 809cases

Just remember there is a weight limit, 60 pounds. I have a reloader on my route, I hate it when he get overtime. One week, cases like 5 of the big flat rate boxes, next week lead in the same size box. Almost rip my arms off if I don't check the address first. If you go to you can order boxes for free.

PS For your and the other persons mailman right HEAVY on the outside LOL

Are you guys this good with questions about women too?
Why, do you need help with them too?

BTW, the weight limit is 70lbs domestic, 20lbs international for the flat rate boxes.
