I am looking for info on sorting brass by web thickness and/or case weight. What specs do you guys use to sort 7.62/308 Win?

I can't find the thread again but I have the picture from the member here that sorts 5.56/223 by web thickness where he creates three pools of brass by measuring the web thickness using a 2" steel dowel:

Greater than or equal to .185"
.175" to .184"
Less than .174"

I made a hardened steel dowel to use to sort 556/223 but I am just curious as to if anyone here has a tried and true method for sorting their 308 brass.

Life's too short.

Unless you're shooting for zillions of dollars in prize money, sort by head stamp. I've done case weight and it's a lot of work keeping track of things when I'm loading lots of rounds.

IIRC.......that thread was about Fed .223 Rem. cases. And discovering the Fed cases that were made with a "thin head/web."

Not so much for an accuracy purpose.

Aloha, Mark

5th post in this Thread for the web measuring you speak of.

I haven't heard of any problems with 308 web thickness.

So I only measure FC 223 brass.

308 FC cases are my least favorite because the primer pockets loosen fast.

I much prefer LC, Win, or Rem brass.

Unlike 223, reduce loads 10% when using LC brass. Loading manuals are correct in 308 cal.

In pistol brass, FC is my favorite brass.

Thanks guys for the advice.
I'm not really sorting for weak brass so much as consistent case capacity. I was working up a load last month using 110gn Hornady SP's and IMR4895. All of the data I had showed the max load to be at or above 50 grains. The problem I ran into was using CBC (Magtech) brass, you can't fit much over 49 grains of IMR4895 into a CBC 308 case.

I have since switched to H335 powder but I am wanting to still maintain a consistent case capacity. It is probably not needed but It doesn;t cost anything but time to add that step in the process. I am loading small batches for a bolt rifle so it isn't too big of a deal to sort a 100 or so cases to get 40-50 within a certain spec.

Personally, it is a waste of time.

Mark , i read your posts with respect, but, wouldn't checking an sorting per case web thickness have a bearing on accuracy to an extent because of different pressure created by different internal dimensions. jim

I think what you want is to weigh the cases and separate into "lots".

An inexpensive digital scale is great for this.

That's a heck of a lot of effort, especially considering that you're not even using premium bullets.
