Loaded Ammo Weight

[kimbrel425@yahoo.com]

Assuming I add the bullet and powder weight together, what is the average weight I should use for 9mm and .40 S&W brass to get an average overall weight?

Considering the bullet weight variances and case weight variances you would only get roughly close with this proposed method. With the close tolerances between piff/bang/BOOM! I would not trust this method.

For what purpose are you doing this?

Maybe we can shed some light on other methods of whether or not it's a good idea.

Go look up brass weights for cases. That should tell you.

I hope it is not being added together AFTER it is loaded though, because if you have no clue and base weight after it is made- you are asking for problems AND for someone to come hunt you down after you make a sale...

It won't work. I've seen 9mm cases vary by 9 grains or more, so any 0.2 grain discrepancy in the powder charge or projectile weight that you're trying to catch will be buried in the other variables.

All of the components vary in weight. Variation is linked to brand and quality of the components. Your powder should not vary much more than .1 to .2 grains. I personally would not trust this method for gauging the case powder charge. Upon reloading, I look into each case to confirm a charge has been placed. Other than that, I don't care what the final round weight would be.

If you have another reason (other than charge weight) to be considered let us know.

So how do I check loaded rounds to do make sure they aren't double charged? I like my hands too much not to ask 😁

Depends on the powder and bullet. You could say have heavy bullets with a light charge weight and double charge...
Why don't you double charge a case and see what the case fill is.
Some powders will spill over and some will not.
If you are loading properly, there is no way that can happen.
Visually inspect each case before you stick a bullet in there!

Currently, how do you check that the case is primed? How do you check that the 9mm case is indeed a 9mm and not a .380? How do you check that the case even has any powder before you seat the projectile? How do you check that you used the correct powder?

Figured this is where we would end up.

You pull them apart. If you have any doubt about the quality of your loads, you pull them apart. You don't take shortcuts. You don't guess. You don't try to outsmart yourself. You pull them apart.

You cannot weigh them. Too many variables for it to be even remotely accurate with pistol rounds.

Brass weights vary too much to be able to tell. I use about 3.2 grains of titegroup for 9mm. The brass weight varies more than that between different manufacturers.

Easy.
When reloading, you are using one brand of case, bullet, powder.
Since your powder is precisely measured, you can ferret out a double load.
Measure ten completed rounds and you'll be able to see the odd one out.

Good info, thanks. How many here don't use a digital scale? Thinking about just sticking with my Lee beam

Weighing loaded rounds as a QC method is DANGEROUS!

If you want to check for double charges, and that is a very smart thing to do, you look down into the cases after you've charged them all, assuming you are loading on a single stage. There 100's of books on the subject and thousands of posts covering the reloading process. For Gods sake, read one of them!

And if you have to ask the question, I'd highly recommend you disassemble every round you have reloaded that you are unsure of.

Lee beam scale was....

Well i trust my cheap digital more. But i trust my rcbs beam scale more. Buy a Gempro 250 or a nice beam scale. They5re worth the investment
