.223 brass

marlinm60ss123 · December 12, 2011, 08:30 PM

my friend told me today that you can trim 223 brass to a make a 308 round. is this possible?

DiscoRacing · December 12, 2011, 08:35 PM

LoL...

no... by a long ways no..

not even close to the same diameter.

Are you sure your friend didn't mean trim the 223 brass to make a 380 ACP?

marlinm60ss123 · December 12, 2011, 09:40 PM

thats probably what he meant. i dont know though. people were talking in the background

marlinm60ss123 · December 12, 2011, 11:50 PM

he actually meant, sizing and trimming 223 brass into brass for .300 ac blackout, or 7.62x39

Hey Marlin,

I think someone is still getting things mixed up. You cannot make .223 brass into 7.62X39 either. The Russian round is much bigger than the .223. As for a .300 AC Blackout, I have to say that I do not know what that caliber is.

Best wishes,
Dave Wile

yup can make 300 aac out of it for sure..... 308 no way not even on a good day!!

I think he meant to say you could use the 223 and make 7 mags! Just joking. Just resize them and leave at 223 until they're useless and then to the scrapyard.

That would be one heck of a fireforming trick. Can I watch...........from a distance?

Ummm.Not unless your god.If you did manage to do it (never),Wow would that be some thin brass.

Apparently, you "experts" have NOT heard of the .300 Whisper. While not technically made from the 223(it uses the 221 Fireball), it COULD be made from a .223 by shortening considerably.

.300 Whisper

That is a far cry from a 308.

Mobuck · December 15, 2011, 10:03 PM

It DOES use a .308 diameter bullet so in one aspect, IT IS A 308.

4runnerman · December 15, 2011, 10:36 PM

very true mobuck. I stand corrected.
