7TCU back to .223

[Judan_454]

I got a mini 14 as early Christmas present but is really hard now to find .223 cases for reloading. I do have a bunch 7 TCU which I made from .223 cases, I was wondering if there was a way I could size them back to .223 ?
Thanks Dan

how much brass do you need?

oh, sorry, yes you can size it back to 223 but why? there is LOTS of 223 brass around for cheap.

With a little patience, you should be able to find more than enough .223 cases to offset your 7mm TCU conversions.

It would make much sense to offer them in a trade for what you seek.

I would also think that expanding and then necking that brass down will cause neck issues much sooner than not as well.

Already fireformed 7mm TCUs should trade pretty well for 223 brass if I am not mistaken.
