40 SW case weight variation?

[hubcap]

I did a random weight check on my 40SW brass (assorted headstamps). It was cleaned and unprimed--just the brass. I checked the case length and they were the same, but as much as 10.5 grains difference!!! Is that too much? I don't usually sort handgun brass, but should i?

I would certainly sort .40 brass, especially if I were loading near Max loads.

But myself?

I sort everything.

RC's Rule #3:
It's easier to sort out problems with sorted brass then it is to sort out problems with unsorted brass.

Brass is not typically consistent in weight from piece to piece. I shoot tons of 10mm (slightly higher pressure than .40 S&W) and I don't bother weighing the cases at all. The only thing worth weighing is the powder charge itself. If you're really concerned you can weigh the bullet too, but I don't personally see the point.

Alright, I'll bite
what are Rules #1 & #2

Or do we have to "stayed tuned" ?

I really don't have any rules.
It was a word play on Gibbs Rules from NCIS!


But in 50 years of reloading, I have found most reloading problems I have had over the years were head stamp related to one brand.

So simply sorting by headstamp while inspecting brass can save me a lot of hair pulling if I suddenly start having problems.

rc, which 40s&w headstamp(s) do you normally select for near Max loads?

Excuse me, but that Rule is taken

40 S&W brass variation

In no way do I have the knowledge of the others that gave you a reply . I only know that sorting by head stamp sure makes a big difference in 380 loads.
