I was at the range today, shooting j word reloads. got to the last set of five, inspected the brass. on was missing it's primer looked at the other 4. no budge or flatting. I know I was under the max book load. I prime my brass with a lee hand primer. was noticing some where falling out after setting the primer when I did the last lot.

Here lies your problem/s as I see it. Primers falling out = Might be time to toss the brass due to enlarged primers pockets. You could try a different brand of primer to see if they fit tighter. Range pickup brass = There's usually a reason it's laying on the ground. Personally I tend stay away from it.Quote:

I get most of my brass once fired from the police range after the yearly quals. (Friends with the Sergeant) and while thier duty rounds are Remington, thier practice rounds are Winchester with a crimped PP...the pockets are very loose if the crimp isn't removed very carefully.

I bought my 300BLK brass from this fellow, one of our fine vendor sponsors. It's made from once fired from a military range. It's good stuff, and NO loose primer pockets!

One advantage of depriming my rifle brass with a universal die in a single stage press is that I know when a primer pocket is loose and can toss the brass in the scrap bin without further processing. Hard to feel this on the progressive, at least it is for me.
To accurately gauge a primer pocket the plug gauge must be a double D configuration. The flats are required to detect an oval or chicken egg shaped primer pocket.
The egg shape can be on size in one axis and gauge ok with a round gauge.
The double D plug gage can be rotated to find the large axis of an egg shaped primer pocket.
I know a lot about gaging from a career as a manufacturing engineer. However it is rare for me to gauge primer pockets.
I always knockout primers with a hand punch and I prime with a hand tool. I can always feel a loose primer pocket.
If I find one that is loose I can verify with my gauge and then crush it so it cannot be used.
I use a frankford arsenal hand deprimer. hit an second bad primer pocket. put it into the collet and the primer came out in my hand. scrap for that one.Quote:

Hope you didn't scorch (burn ) the breach face.
19.3gr is well within spec. It’s not like you can double charge that. Toss the brass in question and check the others.
Yep brass prep is a pain Crimped primers are sort of harder to tell coming out. As someone mentioned the crimp can hold it tight while the pocket itself is loose. A go no-go gauge would be useful. I use the CH4D primer pocket swager to remove crimp and that gives me a pretty good feel for the pocket tension.
Between de-crimping primer pocket, trimming, annealing and finally loading about the only way .223 save me money is by keeping me from having time to fire any. Save a lot of expensive powder by not getting to the range. :-(
Range P/U may not be the best brass but if one is careful it can be the best way to accumulate a good stash. Having a couple of 5 gallon buckets for any autoloader is a good place to be. Even if one has to ditch some as defective. Good processing and good inspection are required anyway for reloading so..... I may have to get a third bucket just to make sure I don't die without having some work still to do.
Loose primer pocket. Nothing wrong with the load if it is safe and within manufacturer load specs. There is a tool to fix loose primer pockets in shotgun shells. I don't know about rifle and pistol tools that do that. Easy peasy solution is to toss it in the scrap bucket.
God Bless, and One Love.

The problem with the brass is more than likely it is 5.56 brass fired in a out of spec chamber by the previous owner. When 5.56 brass is fired in a non spec gun the primers will fall often fall out. I became aware of this recently and that many SO CALLED NATO spec guns have chambers which are not cut correctly.
You had one bad case out of how many loads? More than likely the problem was from a bad case...
Fire around 50rds. It was part of the last set and most accurate grouping

OPB Other Peoples Brass. aka unknown abuse or misuse.
