How to ID .223 and 5.56 Brass Head Stamps

I just received and I’ve starting cleaning 100 pieces of .223 and 5.56 brass. I have not taken a count, but many seem to have crimped primers. I will be better able to make this call after they are cleaned. Some of the cases have .223 stamped, but many others have markings that I am not familiar with. So far, I have not seen 5.56 stamped in any of them. I have not yet gone through them all.

How do I identify brass that are not labeled with .223 markings?
It is an assumption that if it is not marked .223, it is by default 5.56?
Are there any online resources that can help?

I‘ve looked through my reloading manuals, and there is nothing there that helps. This will be my first rifle reloading. I am starting with learning how to identify the brass.

This page will help identify the manufacturer:

...but I'm not sure that's what you're asking. Ultimately, it's going through your die, so they'll all be the same externally. The only difference will be internal volume. That's why you separate by headstamp (you can use mixed brass, just don't push max).

If it's got the NATO circle cross:

You know it was 5.56mm and it's a good bet the primer pocket will need to be swaged or reamed out.

You guessed right. I want to know what the codes mean. And yes, I did see some cases with the crosshair symbols.

Just be aware that Federal .223 may be crimped. The stuff I bought at Wally World was crimped.

You might as well assume that it is all crimped until you have loaded it for the first time. That way you don't risk overlooking some.

Yeah, I am making that assumption. What do you use to remove the crimp?
I use a Dillon 1050 to reload .223 since it has a swaging station. I size and trim on a 650 because it is fast to set up. That is not a practical approach but it works really well.

The Dillon Super Swager is my choice for manual swaging. There is a spring return modification on YouTube that is worth considering.

I don't want to remove metal so using a reamer is not my first choice.

First a point of clarification, the crimp is not a ring that is pressed into the pocket, right? It is a deformation of the brass around the pocket, right?
Actually, I have seen it done both ways. I always doubted that Federal .223 crimps were actually 'crimped'. It seemed more like they were trying to correct the pocket diameter by pressing a ring alongside the primer. Nevertheless, a new primer won't seat very well.

I use an RCBS Swaging die set... takes some fiddling, but so does everything else.

The Dillon Swager is really nice if you have the money and space on your bench...
But due to the motion of the handle, I think it takes less space than the RCBS bench swager.

I have the swaging die set and I never really grew to like it. It will do the job but it seems to be a good deal slower than the Dillon Super Swager. Maybe it's just me...

I didn't know RCBS had a bench swager.

As far as the swaging die, I think it's you. You set it up, and load brass in one at a time. On the Dillon, you set it up and load brass in one at a time. One is on your press, one is in its own housing bolted to your bench.

I have the RCBS bench swager, it works pretty well but I must admit from the vids I've seen the Dillon unit looks like a better setup.

I like swaging better than reaming out the crimp myself.
Reaming works pretty well on the stab crimps but ring crimps can be stubborn to ream as it seems a lot more material has to be removed than I like.

The Dillon swager doesn't have to take up a lot of space. I mounted mine to a board that I clamp to my bench when I need to use the swager. It lives somewhere else when it's not being used.

This is sort of what I did except I drilled a hole in the top of the thumb lever and install a cotter key. Then ran a spring back to an L hook.

Somehow I got the idea that the Dillon approach was less fiddly and that the arm motion (moving the handle) was considerably less. I also thought the Dillon was just plain faster.

It's all moot! I converted my 1050 to .223 so swaging is free. Well, except for having to buy the conversion to .45 ACP for my 650. I guess nothing is really 'free'.

I think I would prefer something that I could install to my press, like this item seems to work.

Any comments on the functioning of this item? Sadly, it looks like this requires a single or turret press in order to use this tool. So maybe I cannot use it after all. I have a Lee Loadmaster.

Yes used them a long time ago. Works okay if you only have 100 or so. And you need a SS press. Dillon works 100% better.

You gotta get out more ZOmbie. I have the RCBS, works fine, sometimes it still leaves a little of the crimp behind. So either swage, turn the case 180gr & swage again or I just clean them with a VLD style deburring tool. I had the RCBS die set, painfully slow. I just mounted my RCBS swager to a chunk of 2x2 & clamp it in my bench vise, remove it when done.

I must be talking to a brick wall. It's like I'm having a conversation with Little Stevie or something.

I am looking for an effective way to ease into reloading rifle brass with military crimps. I cannot (least right away) spend $70 to $100+ on a bench swaging tool. I am not sure I will be processing that much rifle brass. I cannot use one of those tools that installs on a single stage press; because I don't have a single stage press. I have a Lee Loadmaster progressive press.

I am looking for suggestions that eliminate the two choices listed above. At least for now. For now, I have 100 cases I need to process. For now, I may be processing 100 to 200 cases per month.

I am looking for other options. Are there any good options? Meaning option that have worked for you. Options that don’t require spending unreasonable sums of money for the small numbers I am currently looking towards. Options you have had favorable experience with.

I’ve been looking on YouTube and people are using counter sync bits on drills, hand reaming tools intended cleaning primer pockets, where others are pocket knives (Yeah! Not trying that one).

I have no experience with processing military brass. I’ve been reloading nothing but handgun brass for the last three years. I need some help easing into rifle reloading.

BTY, I will be using my rifle brass with an AR15. The brass I need to process is a 50/50 mix of .223 and 5.56. Nearly all of it seems to have crimped primers.
