Rifle Cartridge Cartridge weight kilogram

7.62x51mm 393 gr
5.56x45mm 183 gr
7.62x39mm 281 gr

You'll have to do the math!

393 grams is like 13 ounces so that is not right. A pound per round? Maybe that is in grains, which isn't metric.

gr = grain
g = gram

There are ~7000 grains in a pound. So at 393gr per round, that's about 18 rounds per pound.

Honestly 393gr sounds a bit high, but I've never measured one.

right, but smle man had kilogram in his table header. Anyway, pratt sounds sort of right, but I kind of think 880 rounds of .308 would weigh more than 44 lb.

Just weighed my German DAG .308 in at 0.85 ounces. That's about 18 rounds per pound.

From CARTRIDGES OF THE WORLD, 12th Edition, U.S. Military Ammuniton section, p. 501.

M80 Ball Cartridge weight is given as 392 grains(max). With a variation of -31 grains. Meaning from 361 gr up to 392 grains max.
Case: 190 - 20 grains
Bullet: 149 - 3 grains
Primer wt: 5.43 - 0.52 grains
Pellet wt: 0.60 - 0.12 grains
Powder wt: 46 grains(Ball)
41.5 grains(tubular)

7000 gr/lb /382 gr/rd = 17.8 rds/lb x 11 lbs = 196.4 rds
7000 gr/lb /361 gr/rd = 19.4 rds/lb x 11 lbs = 213.3 rds

So, depending on the rough weight range, from 196 rounds to 213 rounds, if you are dealing with a 150 gr bullet. Mil brass is supposed to be heavier than commercial brass, so depending on whose brass you have, you may get more rounds in the 11 lbs you are asking about.

Thanks for the info that helped.

My .308 round weighs 370grains or 24 grams
11 lbs is 4,989grams
so it looks like i can bring 207 rounds with me on the plane. I doubt that will last me 12 days of free shooting in the orchards in Michigan

I've heard you can only bring ammo on planes if in original boxes (maybe someone else can confirm that, or tell me I'm full of crap). My Silver Bear 140gr .308 weighs out at 15.9oz per 20 round box. That would mean you could bring 11 boxes of this ammo, or 220 rounds unopened.

I have german mil-surp that weighs 17.7oz per 20 round box, which would mean you could bring 9 boxes or 180 rounds unopened.

Most airline regulations say original box or similar packaging that holds indivdual rounds seperately.

That's not quite correct. The ammo just has to be packed in a container that is intended to hold ammo. I have flown several times with 9mm and .45 ammo in plastic ammo boxes like the MTM boxes with no problems. Who keeps the original cardboard boxes? The ammo has to be in the checked luggage, and if you are not declaring a firearm, you don't have to declare the ammo in the checked luggage. I flew from SFO to DCA on Wednesday, so my experience is very recent.
