Finally got things dialed in to load 9mm on the l-n-l with case feeder and bullet feeder tubes. Loaded 100, plunk tested all and will get to range in next few days. If all good, run a large batch.
That is awesome! Goodonya.Loaded 300 rounds of 9mm gonna take my older bro shooting for his birthday. He hasn't been on the range in over a decade. We're going to Cindy's/On Target. Turns out last time we went his wife was pissed she didn't get to go and got left with my ex. So she's going along with this time. She has been talking about getting a gun so we'll see how that goes.
LC brass primers are crimped. The primer hole needs to be trimmed/swaged/reamed/chamfered to remove the military crimp. The crimping is done to prevent primers from popping out during full auto fire.I reloaded 3 different velocities of 5.56 for testing. Hornady 62gr freedom seeds for my 1x7 barrel.
I had more difficulty priming these than my .30-06. The Lake City brass holes seemed off center and the primers wouldn't enter some of them. Others had what looked like a sleeve and the primers wouldn't enter. I'm going to re-run these through my case prep machine to see what happens.
It does make sense. The crimping is usually visible to me. Maybe I'm not seeing it. The primer hole looks smooth all the way around but looks...off center. It's almost like the primer arm isn't lining up with the hole because of this. I'll try to post a photo later.LC brass primers are crimped.

ETA- I have been taught that military brass that has a code on the headstamp (vs. manufacturer name and caliber) will be crimped. EX: "Speer .223" or "Win 5.56mm" headstamps likely aren't crimped. However, "LC 13" or "IWI 21" will be crimped. I hope this makes sense.

Ah, nice. No, I need it for small rifle. It's my 5.56 that's giving me fits. The .30-06 was fine.Get this, but for large rifle primers.
I apologize. I misread your post.Ah, nice. No, I need it for small rifle. It's my 5.56 that's giving me fits. The .30-06 was fine.
^^^ This plus you will also run into "Staking / Stabbing" which consists of 3 separate crimp marks around theLC brass primers are crimped.

I get rid of those - I've had powder gas leak out of those, which is probably because I cut out my crimps rather than swage them. I'll have to get a new bolt face for my precision gun at some point because of it, so now when I come across them, for better or for worse, I just toss them out.^^^ This plus you will also run into "Staking / Stabbing" which consists of 3 separate crimp marks around the

Thanks...U.D. was gonna post some but ya beat me to it.Examples of stake crimped primers being mentioned. Note the stamped indents shown.
These Staked/stabbed crimping can be 1 to 4 indents. There may be others as well. A close inspection of cases will indicate what's crimped and what isn't, once one knows to look for it. The primer pocket go/no go tool mentioned by 4g64loser made by Ballistic Tools is a godsend to help keep you from going bug eyed looking for ring crimps and the different stake type crimp configurations. I think mine were 10 bucks each for large and small. Worth every penny.

@ trickg...
Interesting about the gas leaks around the primers, never had that issue (yet) use a counter sink to remove the crimp, not a reamer that most companies reloading orientated sell, have swaged them also with no issues. No precision rifles, just plain jane rifles 788, 700, and various semi's. We are just talking LC-12 cases, 5.56.
