Until recently I've never bothered, but it occured to me that running new brass through the sizer die is an easy way to "uniform" it a bit... also easily takes the dents out of the case mouth's.

What'd you do?

Brad

I do....and you just stated my reasons for doing it.

I take special pains to do it on rifle brass for sure ... for the reasons mentioned.

I run pistol brass through a Dillon 1050 progressive so it happens anyway.

I always do, in order to have clean uniform brass. I size, trim, de-burr etc. with every new batch. It's a good idea I think to examine each case. We've all probably found bad brass. Though it pains us to have to discard any. Jim......

Me too.

And find the shortest case in that batch, then trim them all to 0.002" less than that, so they're all the same length.

And deburr the flash holes.

And sort by weight.

And segregate the sorted cases in various increments (.5 grain variation for match type stuff; 1 - 2 grain variation for hunting stuff), with different colored Sharpie lines in the extractor groove to keep the segregated cases together, but separate from the OTHER segregated cases, each in their own little Baggie, to be marked with the number of times each baggie's contents have been fired.

Now, if I could just figure out a way to mark each individual bullet for weight, dimensional variations, etc... AAAAARRRRRGGGHHHHH It's a sickness I need help.

i do. and then trim to length and deburr (when I feel like it needs it) the inside primer

It all depends...........if loading for an autoloader or lever action I wouldn't bother.

With norma or federal gold medal all you have to do is run a sizing ball or lyman m die into the mouth and then procede to build ammo that will not have more than .003" runnout.

Win and rem brass are a different story--depending on the lot I might resize if really trying for a super accurate load in a bolt action.
On this brass it would be likely that a resize would cut runnout in half.

PS--if a guy is deer hunting in the woods it would certainly not be necessary-----but trying to get runnout down for long range shooting might be a good idea.

I use a tapered punch to round out the case mouths on new brass.

R-WEST Yor're sick all right! BUT reloading is the cure!!!!

I always have with a little dry neck lube on the expander so as not to stretch (lengthen) those that are way out of round.

I didn't used to but after I noticed the case mouths were not uniform I started. I simply run my die up and only neck size. I have full lenght resized new cases but I haven't noticed a difference.

I didn't in the past, but generally do now for the above stated reasons.

R-WEST, the way that I permanently mark cases to keep them segregated when all else looks the same, is to use an automatic centerpunch somewhere on the letter/number on the casehead. For example, I have some LAPUA brass sorted in to three groups - "light" has a punch on the "L", "practice" brass has a punch on the "P", and "heavy" brass has a punch on the "A". Makes it easy to separate when I tumble a bunch of it together. It kind of flattens out after several firings, but still has enough of a mark to be able to see it. Don't do it in the plastic ammo box, though, has a tendancy to cause cracks. I usually place the mouth of the case on the anvil on my bench vise, and hold it tight.

Most definitely. Preferably with a neck size die if i have one in that calibre. New brass necks very often are dented.

Then I trim to uniform length.

I do, it will not chamber in my rifles if I do not. But I was told from day one new brass was to be FLR.

On new brass, I neck size only.

BRAD,
Whenever I get a new rifle, I also buy one box of factory ammo. I use these to adjust whichever scope I put on the rifle, but what I consider more important, I use those cases to adjust my body or full length sizing die so a sized case ends up with with the same headspace measurement as the fired case. I also replace the expander button with a tapered button to make it easier to remove neck dents on virgin cases. I hope that this is of some help. Good luck.

Me, neck size only. I also trim so they are uniform to start with.

Me, neck/mouth size only!

I full lenght size and trim to the shortest case

I size them and have been deburing the flash holes too. The last batch I also trimmed. This gives me a chance to check the brass over also. I did have some goof ones in the past. One was a neck that the brass was folded over weird. An extra step but worth it
