X-die for 223

[ninefan]

Yes Danny, that means the dies are working. Notice that the case didn't grow at all after sizing, which is usually one time where some case growth happens.

They will grow slightly the first firing or two, but the X-die should keep it in check if it expands much after that (.002-.003 is nothing since RCBS wants you to trim them .010 shorter than normal to begin with).

Don't change anything about the die setup and you will be good to go.

Thanks for the reports it looks like you might get 7 loads before trimming,not bad.

I wonder if the brass will last that long... since the brass flows to the neck and gets thicker... it has to start getting brittle at some point i would think.

I usually anneal the brass after the third loading. If it gets thick enough for me to consider neck reaming it, I will probably put it in a bin for winter when I spend more time at the loading bench than I do shooting. The only time I normally neck turn or inside neck ream is when converting brass to a smaller caliber, such as making 6.5 swiss from 30-06 brass. I have reamed 7.62X51 military brass when converting it to .243. Blitzfike
