Best way to deal with crimped primer pockets? I have about 200 Hornady once fired 300 BLK brass that I hate to not use but these crimped primer pockets are a bear!

A swager is best, but a debur tool works just fine.
i think i have a lyman tool that i chuck up in a cordless drill
i try to stay from them

I just use a counter sink bit in a cordless drill. You don't have to take off a whole lot. Just enough to remove that edge and leave a nice bevel. I have never had an issue and have done plenty 5.56 mil brass this way.
I chuck one of these in a drill and cut them out. Works great.

That's what I ended up using. I wasn't smart enough to use the drill. Took me forever to get 100 of them done

If you have range brass with mixed headstamp, a swager may not be the best bet, unless you presort all the brass and setup it up for each different headstamp. I have been using one of these debur tools. Threads in.That's what I ended up using. I wasn't smart enough to use the drill. Took me forever to get 100 of them done
I find my Frankfort Arsenal machine just doesn't cut fast enough to be productive on primer pockets. Does good on the debur tho.

I do have to apply a little pressure for it to cut fast, but it does ok. I may have to try a drill and see how it does.

Several years ago I purchased 4,000 crimped primer pieces of brass. Could not understand why the price difference and even headstamp selection was so different. You know the commercials/movies where the male lead actor has a job to do and he keeps on ignoring it and the ignored task develops a devilish personality?????????

Now I know.
1. Walnut tumble to get brass clean enough to put into die.
2. Decap & FL size
3. Jam several in FL die. Discover machine gun brass comes from weapons where the term loose chamber came from.
4. Acquire SB dies for 223. Get two backup universal decap dies.Get extra case lube. Get Kroll oil.
5. Complete decap. Some are Berdan primered. Unreal the misery this can cause. I hope mr berdan is smiling in his miserable grave.
6. Using SB die FL size all 3800 (200 tossed Berdan primers. Went to supplier, asked, received replacements).
7. Measure case length Oh no need to trim to length 6 of 10 must do all. Wear out my Lee blades have to order more.
8. Get all 4000+ , decapped, SB sized, trimmed, now must chamfer inside and outside case mouth. There are 1/8th moon spirals of brass that slip directly under fingernail.
9. After manually removing walnut stuff from flash holes I give up and get SS outfit even thouh Mayo jar does not contaiin necessary funds.
9. COST: Too much to count.
What did I learn? never ever buy crimped brass unless you have a broken something and are housebound.

I done something similar once or twice. My 223 brass was mixed. I hand sorted and got them figured out. Other than the occasional missed crimped primer pocket, it's not bad. My trouble was 45acp brass. Large primer vs small. Part of those are crimped lol. Just this weekend, working on 9mm getting ready to load. Half of the win brass I ran into wouldn't fit in my shell holder good. Stuck three of them because the rims just folded up. Finally just threw that shell holder away, and May finish throwing the win brass out too.

I use LC brass a lot, both 5.56 and 7.62 and all mil brass is crimped. I find that my bits in the Lyman Case Prep Station handles them real well. I had to use the VLD deburring to knock out the new stake crimp I ran into, but otherwise they worked great.

I have 10s of thousands of once fired LC brass from machine-guns and have used the Dillon Super Swage on a few hundred over several years. A while back I came across some R-P .223 brass that was clean but not deprimed. Apparently at some point years ago I bought several thousand of these cases (probably late at night and fueled by al-kee-haul) and even though they have the deflector dent in the case, they are not crimped. Gonna soon be shooting some that I loaded Saturday.
Man that Lyman case station is some of the best money I've ever spent for my loading bench!I use LC brass a lot, both 5.56 and 7.62 and all mil brass is crimped.
