Resizing new cases

[Hair Trigger]

"Over working new brass"?. How many reloadings before failure for one additional resize? I rarely guess at anything or take anything for granted when reloading. Cartridge cases are mass (!) produced and not every piece is inspected 100% and is is normal for an OOPS! to sneak through. Although I can't remember a bad case from Starline, one pass through the sizing die does not "work" the metal and gives me one more look at the cases. Even on a single stage press, it ain't no big deal. But if you don't want to, don't. I prefer to...

I can't think of a single instance in my shooting life (since about 1975 or so) that I had a cartridge out of spec enough that it wouldn't chamber, either with new ammo or properly sized reloads. When I buy new brass for reloading, I get a quality product, which in itself doesn't mean there won't be an occasional bad case in the pile, but it definitely decreases the odds. I get plenty of chances to inspect each case when priming and flaring the mouth for defects such as a crushed extractor groove or bent rim or flattened mouth, and set them aside if repairable, or pitch them if not. I just see no reason for the extra step of sizing a case already sized. I use a single stage press, so that one step alone saves me a ton of time when processing several hundred rounds at a time.

Well, chamber dimensions in revolvers can vary wildly, it's almost impossible to know if you need to re-size or not unless you use that really expensive NBRG device (New Brass Resizing Gauge) that you already own to determine if you need to resize that nice Starline brass.

In other words, try the new, unmolested, unloaded brass in the chambers of your revolver cylinder, they should drop right in......and if not, well......you know what to do.....

Most new brass will be fine as is, butt it doesn't hurt to check.
And why would you check some industry number measured with a caliper when you have the actual cylinder of the revolver you are reloading for handy?
Assuming you are reloading for One Gun and not running an at home APL (Ammunition Production Line).

I can't recall if it was the last order of 500mag or44 mag brass I got from Starline, but the lengths were all over the place, +/- .005", and many mouths had chatter marks. Regardless, I sized and trimmed as I always do with any new revolver brass.

When I bought some Starline brass a year or so ago, the website stated that their (pistol?) brass was ready to load as is. Just sayin'.
