It's all FMJ for a class this weekend. I can't tell you what it weighed, but it all filled the bed of a Mazda B4000 4X4 pickup truck that didn't have any problem driving the 10 miles to my house so we could off load it.
I've had 50,000 rounds of AK ammo in boxes of 1k in my Rav 4 before. We drove it from Louisville KY to Knoxville TN. I'll grant it had the little critter squating almost all the way down on it's springs.
And, yes, I did think about what a traffic stop would look like in both cases.
