Nothing special, no big rush. Just if you think about it and you're sitting at your reloading bench and you have a scale handy toss a few empty, uncleaned and still primed cases on the scale and post the number of cases and total weight.

I don't have the neccessary tools and I wonder if my very cool chemistry professor would object to me tossing a few empty 9mm and .40 S&W on a scale in the lab.

I went a weighed 3 338/378 cases that I had (with the old primers still in them) and they came out to 321.4, 322.2, 323.1.

Sorry, all my brass is loaded!!
I did weigh available .40 SW cases and 9mm cases.
-RP .40SW case with spent primer 69-70.3 grains each
-Win .40 SW with spent primer 70.4-70.5 grains each
-9mm RP and Win case with spent primer weighs 61.3-62.1 grains each
Overall lengths of these cases will cause a little variance in weight and some other cases from Fed or Speer or S&B can be a little heavier.

thanks guys :) varience is what i'm looking for. trying to figure out the average count/pound from real world numbers and not the internet.

I have some ordinary Differential Equations, Nonlinear Systems of Two Equations, used to compute the velocity of a projectile. Will you do my computations? If so, it will free up my time so I can find the time to do your simple math.

Since I have already finished my financial projection on all three of my construction projects, and will noy have to do them again for 3 weeks, I took the extra time I had on my hands and weighed some 45 ACP cases.

.2 oz per case
87.5 grains per case
5 cases to the ounce
80 cases to the pound
800 cases to the max capacity of my postage scale (10 pounds)
160,000 cases to the ton

P.S. I calculated the last one, I was a little short having a full ton to actually weigh.

I think I am bored....... Let's go shoot...

How do you account for the ones that are no good, and you have to throw away?
