Stupid question about 5.56 brass

[Doc Harvey]

Just sorted all of my .223 and 5.56 brass, separating one from the other. Ended up with 96 pieces that are staked differently from the rest of the 5.56 brass. Is this stuff reloadable? Thanks.

Stupid question addendum: If reloading for 300 Blackout (which I am not doing yet) can one use both .223 and 5.56 inn the same manner, or is there a difference between the two?

I don't see why not. Need to make sure you swage or chamfer the primer pocket for that crimp.

Look down the inside of case to verify it has one flash hole, then de-prime it, swage it on a Dillon Super Swage, size, trim, and reload.

5.56 brass has a thicker wall, which means a smaller case volume. If you're loading near max, that becomes an issue.

Neck wall thickness when reforming to 300BLK also CAN be an issue. I use a redding carbide neck sizing ball and have not had an issue, as it does a good job of thinning the neck when drawing the ball back through on the extraction stroke.

As was mentioned, deprime and swage the pockets with the Dillon super swager. You'll be good to go!

Thanks very much, everyone!

RCBS Primer Pocket Swager works well for me, It requires less force on a press (for me anyway) speed isn't a factor.

I just loaded up some LC 13 crimped like that last week, after swaging of course.

I wonder why they switched the way they crimp the primers?

I think this is an old wives tale.

I think my comment was based on observed fact. My own experiences and others.

No tale. The brass is obviously thicker. Weigh it once. The outside diameter is the same, so the extra metal has to choke up the inside. Minute differences, but when your talking about these kind of pressures, Every little bit counts.

From the article you linked to:

"Military 5.56x45 brass often, but not always, has thicker internal construction, and slightly less capacity than commercial .223 Rem brass."

Yes but look at the data, the military cases had the highest internal volume.

Way back When ...........when the powder selection was not as great as today,

I selected case brand by volume needed to best fit the powder selected.

My selection for max case capacity was Winchester brand, which was also harder.
Remington brass was next, but it was softer, lasted longer
Frontier brass was thick and hard, replaced by Hornady brass.

Military brass was heavier, thus less capacity after processing like the rest of brands.
Swaging Primer pockets was required.
I cut some cases to remove the crimp, but it affected weight calculations.
I have 2 complete sets of RCBS Swaging setup, and will scrap/sell them. I received a Dillon Super Swage in a trade, Its the BEST for swaging and well worth the price of the trade.

You need to learn how to anneal the case necks and shoulders for best, most consistent, accuracy potential. Turning case necks after annealing will help with the consistency.

Isn't reloading a fun hobby? So many different avenues to explore.

I wonder why they switched the way they crimp the primers?

I could probably find out if you're really interested. I have several contacts at both facilities.

OP: Did these from from LC Independence, MO produced rounds or Federal stuff made in Anoka?
