Weighing empty cases for hunting rounds.

Post by **357cyrus** » 03 Jan 2014 11:36

I know benchrest shooters will weigh empty brass as another control in their reloading process. Do any of you do it for your hunting rounds? Is it worth it? I'm getting ready to load up a few new cartridges for two or three rifles and figured I'd try it. Then maybe test a few of the "culled" pieces of brass against the developed load.

The weight of a case vs the volume of a case is the crux of the matter. My understanding is that they check the weight of water the case holds. In this way the volume is measured. If the volume of one case is X and the next is X + 1 then the second case has more space for the expanding gas to grow in and thus will have a lower pressure than the first case......thus effecting/affecting the velocity.

For me when I used to be finicky it was easier to just keep the new brass of the same headstamp and lot numbers segregated to do the load work up with.

I don't. I do segregate cases from birth (purchase of a new lot) and always treat them as a lot with everything I do to them.

Nice reply D, very well done.

I don't separate cases by weight or volume, but I do keep cases as "lots" from when they were new.

I weigh my .308 cases as i want each 20 or 50 round batch I load to be as consistent as possible. I also keep each batch of brass seperate and carefully track their history. I rarly shot my long distance plan these days but when I do she will reach out n touch somthin no problem.

+I have been collecting military brass for 50 + years.I do try to keep it segrigated as to head stamp but sometimes it gets clumped together (mixed head stamp).
I have not noticed that much diference in velocities but then again I did not have a chrony all those years.
I try to keep data as to number of firings and such but as I do not any longer shoot for score it doesn't seem to make much diference.

If I was a benchrest shooter or match shooter I would take all precausions to make sure they were all the same in each batch I used.
