After you have sorted your cases how do you keep track of the separate groups of cases? Do you mark them, keep them in different boxes etc?

What works for you?

Zip lock bags work for me, all away in the same place but I leave myself messages on the bags

From a BR perspective I just keep them segregated inside my ammo box.

Each segregation I have is set to be for a single group in that sighters and record rounds are all one lot. After you shoot the target put them back into the ammo box as part of their lots. Then when reloading and preparing cases, work on them with the same layout as the ammo box on your loading blocks.

The below image is of my HG cases. The 18 cases on the left are one lot that will be used for target 1 and make up 10 record rounds and 8 sighters. The next 18 across the box are the cases for target 2. By keeping them grouped like this also ensures the number of firings on cases stay consistent too.

The extra 10 cases on the right side are used for barrel warmers / foulers / get on paper rounds.

I keep my brass in zip lock bags. Sorted by brand and number of firings.

They sit it the draw arranged by calibre so I can quickly flick through to find the right amount of cases I need for a reload session.

Just by caliber and then fired or primed and prepped ready to shoot again:

Cheers fellas. Mick, you don’t weight sort?

Only powder gets weighed.

I have never been a beliver in weight sorting cases, as one does not know where the extra brass is situated. I believe that sorting by volume is the way to go, but a pain in the ass, and have never done it. However the other day I weight sorted 120
Winchester .284 cases after being neck turned and trimmed to length. Weight difference between lightest and heaviest was 7.1 grns. I used metho as a media to measure volume difference by weight, and I came up with .8 grn. difference. So needless to say I still believe weight sorting cases is a waste of time IHMO.

I sort my cases by manufacturer and then by chambering.

Hey Trev

Interested in knowing if the 0.8 grn variance was between the heaviest and lightest case you had and if so is what I would expect. I have never batched by volume only weight.

If you have prepped brass through turning necks, flash holes and primer pockets then fire them to chamber dimension (at least twice as the first fireform does not always fully form the case) followed by another skim on necks and trimming to length then the the outer dimension of the case should be to an extent identical. If then you were to weigh them (before any sizing) and batch you would be getting the comparison on the internal dimensions / volume of the case as any variance on brass weight I think would be encroaching on the internal volume.

Hi Al,
That was what I was going to do next. This morning I took a different approach. I took 2 cases the same weight and used the metho method again. A difference of .5grn. was the result. Will be taking the 2 different cases to Townsville next and fire them and reload and fire again, and will do the metho test when I get back home,
Cheers,
Trevor.

Interesting discussion, good test Trev.
So .8gn of liquid is approx .05ml if water.
What percentage is .05ml of the total volume?
About .08% variation in volume after a quick google. To me that is SFA but to those shooting LR they may think it makes a difference.

I've got simpler problems for missing

Bruce

When measuring case volume how to you take into account the primer pocket, flash hole size etc?

Do you leave a fired primer in, tape over the primer opening at the case head or what?

0.05ml may be attributable to how you account for the primer pocket, flash hole, what primer you used, and how deeply seated it is...that is when measuring case volume with a liquid.

Just a thought.

Those clear plastic tubs like you get takeaway curry in. We use heaps of them at work for crib lunches and they only tend to be single use. I take mine home, wash them then use to store cases. They stack well, are clear so you can see what is in them, and cost nothing.

Mostly they stay in their ammo boxes. When excess occurs Kraft/Bega peanut butter jars.
