You make the cases out of 223's. It is a 223 shooting 6mm bullets. When forming brass, I always suggest to start with virgin brass, but you can always anneal with once fired brass (military). Just make sure you are using the same head stamp for your whole batch. You run the 223 brass into a 6 TCU die and it will expand the neck. It expands it from .223 or so to .242 or so; so it is not expanding a bunch. Then load them up for development. Start low and work your way up. I personally would not bother with fire forming, they should headpace OK right off the bat, if not, then you will need to adjust your dies to fit your chamber. Good Luck and Good Shooting

Another name for the 6TCU 6x45.  If you going to use a  FL to open the necks up make sure you lube inside of the necks real good and as LaOtto222 said just load don't worry about fireforming.

It along with the 7-30 Waters are my two favorite rounds for the Contender. It's really as easy as loading .223 as there are no extra steps. I do agree ya need to get some lube inside the case mouth. I do that normally anyway using RCBS spray lube so it's not even an extra step to me.

I've never bothered to anneal even once fired brass for this one and can't say I recall ever losing one to a split as a result tho I do agree virgin brass is best but don't shy away from once fired brass for it. I also don't bother with fire forming and just go directly to load development and have never seen a difference in performance between the first firing and later firings as the change is so minor.

You'll love the round it's one of the most accurate, heck I guess really the most accurate of all the many TC barrels I've owned.
