Have you ever had trouble with your Lee press not pushing certain old primers out?  I finished reloading some "old" brass tonight and some of the primers just had the centers pushed out with the sides left in the old brass primer well.  Drove me apeshit till I figured out what wass up.  Now I know what to look for, but it was a bitch figuring out what was going on.

Maybe crimped primers, or 'cemented' primers.

Is it old miliitary brass?

Could be a bad primer punch too.....or corroded primers.

This is a problem with the cases, not the dies.  Something has corroded the primers causing them to fail rather than being pushed out intact.  A very long time ago I had the exact same problem, I ordered a bunch of once fired 30 carbine cases, they were nice and shiny, but when you went to deprime them sometimes the end cap punched out and left the sides behind, I was unable to find any reasonable way to salvage that brass.  The cause?  The seller had cleaned the cases chemically, there was enough chemical left in the primer after cleaning that it corroded the primer and caused it to fail.  Every single time I have encountered this problem it was caused by using a chemical bath to clean the brass rather than mechanical cleaning in a tumbler.



If someone wants to chemically clean brass they should deprime it first, so that rinsing will remove all of the chemical cleaner, it can't be trapped in the primer pocket.

yep,

like posted above corroded primers, most of the issues I've had are with outdoor range pick-ups that have been in the weather for a bit, on some the decapper punched right on through, those I tossed into the scrap bucket.

like wingman, I've had some "once" fired nickle plated cases that had been chemicaly cleaned without being decapped, a few of the primers were stuck a bit, only the center pushed out, had to adjust the decapper a bit deeper to push the primers the rest of the way out, the primer pocket and inside of the case around the flashhole was green with corrosion,

seem to recall this was with speer nickle cases, some of the speer cases seem to have a concave head too making primer seating kind of a difficult sometimes.

Cool.  I am telling you man....I just about went bananas trying to figure out what the problem was.  How often do you tear down your loader and deep clean it?

usually just spray out the carrier real good with compressed air, unless I spill powder down it, then I take the carrier apart and clean it.


put some lithium or moly lube on the auto index rod about every 1k rounds or when you change over carriers/calibers, doesn't have to be a lot, but enough so that it doesn't dry out and drag through the carrier, and lube the ram every now and then.


HEY! what are you doing posting during school hours, don't you have some school kids raising hell in the halls to harass this morning?

Lunch and planning periods.  Gotta love them.  I get here at 6:30 am everyday so I can have quiet time to work before the little  hellions show up.  The rest of day is spent breaking up fights and drug deals in the bathroom.  On a rare occasion I actually get to teach a little science!!!

norman still had corporal punishment back when I went there, don't know if they still do or not today, I know little axe and tecumseh schools still have it.

hell the little independant grade school I went to before going to norman the teachers walked the halls/classrooms with paddles tucked up under their arms and would whack a kid for being a slacker/smart aleck just as quick as they would for one talking back, then they'd call your parents which resulted in some more ass whipping when they got to the house after work.

as for detention, I'd never heard the term before going to norman, I spent a lot of my 9th grade year in iss for skipping lunch/afterschool detention, which wasn't shit because there was always at least fourty kids there and one teacher/guard.

I did have some pretty cool teachers at norman though, the Oklahoma history teacher used to issue out "dumbness points", you get three of them and it was an hours detention, used to have some heated discussions on what indians did, he finally quit giving me detention since I never went anyway,

funny thing is I ran into him again 20 years later at votech, he was a counciler, I got sent over to speak with him when I completed a course early, he takes a look at me and says "Goddamn I thought your name looked familier", then he says "Mr. Way, tell me, how did you complete a year and a half course in one semester?"

I replied "man I just did the work, if anyone is taking a full year and a half to complete that course, then they're slackers, and if votech thinks it should take a year and a half to complete, then they're ripping people off"

so he says "well I think that course will be reevaluated"

don't know if they ever did anything with it, cause it's still offered there, but I must have pissed somebody off because it took them a full year to get my diploma to me.

didn't matter none though, no lab ever hired me, first thing they'd ask was how I completed the course in one semester and how they must not be teaching what one needs to know if it could be completed that quickly,

that's when I started working in casinos
