Do they tend to split for you when the bullet is seated, or after firing? And if after firing, does it create any failures to extract?Load em' till they split
I have 9mm that's been loaded at least 10 times, probably closer to 20. With mild loads (mine = 124gr @ 1,070) brass will last a long time.
Typically they split after firing, but I've had them crack after sizing. Never an issue with cycling. It really isn't to much to worry about. More worrisome is work hardened brass that doesn't provide good neck tension (thin setback). Why I have sworn off loading anything but full diameter + bullets.
If you're using a single stage or turret press you'll learn the 'feel'.
The splits I've have been after firing. When the brass is cleaned, you can clearly see the crack. If you miss it then, you can tell, because it resizes with no effort. If you still miss it, you'll find it when you seat the bullet and it just drops into the case because neck tension is gone!
That's also when I find most of my split cases. Since I bell and charge in the same die I check the case for powder charge by looking into the case in the next stage. When I look into the case I also look at the case rim for cracks. That's if I don't already see powder spilling from the case.But most of the time I find split brass after it has been resized and after the belling at station 3 on my 650.
I don't do anything at all to sort brass, other than throwing out the split cases I notice. I pick the brass up off the ground, take it home, and throw it in my dirty bucket. When that starts getting full, I start dry tumbling it, 5 gallons at a time.
This is damn near exactly my process too. I use a lee hand press with a decapping die for depriming before cleaning.this is the process I started a very long time ago and yes it slooows the process down but is piece of mind for an old CRB.
deprime on a SS press before tumbling, anything that feels unusual is quelled.
tumble in crushed walnut with mineral spirits and Nufinish car wax added, brass is clean inside and out including primer pocket, easy to inspect.
hand prime, this is where inspection takes place as each piece is looked at for fault, making sure flash holes aren't clogged, checking that primers are seated correctly after seating, when I seat a primer in a clean primer pocket, its easy to tell if the primer pockets are oversized.
split brass is happening at firing for the most part, if it was split before reloading, well, it wouldn't have gotten reloaded, this makes it easy to find and toss.
its the oversized primer pockets that concerns me the most, hard to determine visually with out a gage, time consuming if you gage all your brass before seating a primer but pretty easy to determine when seating a primer.
ya, its time consuming but I usually do it sitting in front of the TV (make seeing the flash hole are clear easy when held up to the TV) away from the reloading bench.
and when I get to the press, priming is done so every step done on the press (LCT) is able to be observed without removing the piece of brass I'm reloading at that time until its completely reloaded and ready for boxing, which is sometimes in an ammo box, sometimes in a coffee can.
