Hi guys I'm fairly new to reloading and I needed a little help so I figured this would be the place to go. Anyway I just bought some once fired 5.56 LC brass and of course they are suppose to have their primers crimped so with some of your advice I ordered a Dillion super swage for that. But after sizing/ popping out the primers I decided to see if I could get a primer in the pocket before removing the crimp. End result it went in fairly easy, whats the benefits of removing the crimp? Do you have to or whats the best advice? Thanks guys Im going to hault my production until I hear what you guys say! Thanks a lot

As to the OP. Remove the crimps. Take the time to do the job right. You should NEVER "Shortcut" when re-loading.

I am sorry you found that so upsetting. It was meant to be numerous. Maybe my sense of humor is out of kilter today.

Some crimped primer pockets are not bad at all trying to prime, but others will flat refuse to cooperate. Best bet is to swage them all, or ream them, but you have the perfect tool to swage them all with. Hope this is more helpful, and I apologize if my post offended. AC

Relax a little and read the thread again, no foul intentions on anyones part, simply being humorous.

BTW, not listening to a guy like Walkalong is your choice, but he has a lot of good info to share, as do a lot of other members of the thr reloading forum.

The crimp helps keep the primer in and from my experience LC has a pretty good crimp. You may get away with not removing the crimp for a while........... But you WILL eventually have a problem. Maybe not a big one, crushed and ruined primer. Could be a startling KABOOM!!!! (safety glasses are a must!) The Dillon SS works wonderfully. Makes the primers go in without too much force. Good luck.

K-Rod,

Please relax. - I think everyone understands sarcasm.
At least I understood that.
And I think Walkalong has LOTS of knowledge and I appreciate it when he shares.

This is the best reason I can think of to ream or swage the previously crimped primer pockets. Primers cost to much to waste. :o

Just out of curiosity, where did you buy this once fired brass from? Did it come cleaned and de-primed. If so, it's possible the primer pockets have already been done.

I finally figured out (I think) what upset K-Rod so much. He thought I was promoting the OP getting a blown primer to "learn his lesson" or something. Nothing could be further from the truth, although I can see now how it could be construed that way.

I have never set off a primer with a hand primer, a press, or crushing them into a knot trying to prime a crimped primer pocket or one I have carelessly lined up in the priming tool, so it never occurred to me that I might lead to OP to setting off a primer. Perhaps that was careless of me and I should have thought about that. After all, we are handling potentially dangerous items when reloading. I shall be more careful. AC

The main risk of not reaming the crimp out is not blowing your face off seating primers.
They will maybe go in kicking and screaming, or maybe they won't, but they won't blow your face off.

What the problem really is, is that excess force shatters the primer pellet, and may flatten the primer cup.
Combined, they may become more sensitive to slam-fires in a semi-auto rifle.

My only experience with an AR-15 doubling or firing when loading happened 40 years ago, before I learned about proper & complete crimp removal, and smashing primers in that didn't want to go with a Rockchuker primer arm.

K-Rod:
As a new THR member of less then two months, you don't know anything about Walkalong, his level of expertise, his sense of humor, or how many helpful posts he has made over four years or so.
Lighten up until you have been around long enough to understand what you are reading from some of us.

Walkalong,

I apologize. I'm a redneck hick from the high-ups of N. Idaho. We don't know anything about being classy. We eat, breathe & sleep firearms up here. You guys all talk about going to the range to shoot or I hear a lot of complaining about you all have no where to shoot over 300yrds. I go out on my back deck & have a two mile shooting lane. Being classy is way over my head but I can admit I was over the top.

I hope we can cyber shake & be done with it.

To the OP - Could be your "once fired" LC brass was not as such and had previously or at least some of it previously been reloaded and the crimp already removed. Could be you received a batch that had very little crimp. There are a lot of variables that could be.
I suppose you also could have just gotten lucky and were able to prime the crimped pockets without difficulty.

Since you have the Dillon Super Swage, I urge you to use it as it's a fantastic tool for the job and I'll bet a dollar to a hole in a donut that over time you will find priming brass easier.

Not all Lake City brass is crimped, regardless of whether it's once fired or not. I bought 2K new LC cases and they were not crimped, and now that they've been cycled through my rifle they are also once fired. If in doubt, swage. It does no harm and since you already have the Cadillac of swagers, it takes very little time to do so.

Good idea. Crimps may or may not be there but also, some 5.56 Nato brass crimps is not so invasive.

LC 30-06 brass has serious crimps and it will tell you so in no uncertain terms.

As you have decided, it is best to remove the crimp on suspected once fired crimped military brass. No harm, no foul and your primers will appreciate it.

Have fun.

You made a reasonable point, if not a bit harshly, but it's water under the bridge as far as I am concerned. :)

When I use my Dillion SS --- I bolt or screw it to the edge of the table--
it makes it easy to swing the handle 100% without having to hold the SS down-----:)
I started reloading to save money---now it is a hobby that I enjoy.
Have fun

Walkalong is right! Primers are getting too expensive. I have a jar to remind me why I remove the crimps........ Jar has more than he shows.

k-rod, im glad you realized walkalongs comment was just lighthearted sarcasm.

since ive been around, i have formed the opinion that he is one of, if not the most helpful, and patient members here.

as far as the crimped primers are concerned, i just trim out the crimp with the tip of my pocket knife.

Lesson learned in the reloading forum I hope!

Glad everyone's getting along but in future this is probably NOT the forum for jokes and sarcasm. Agreed?

Not trying to be snarky or anything, but I hope it's not a glass jar. ;)

I toss my mangled primers. Don't see a need to accumulate them.
