They saiy it works stock for 223 but they also sell a small caliber kit that fits the description of 223....
Maybe the best idea would be to buy the std kit (308), and add the small caliber for 223 and add large caliber for 300 win mag, 338, etc, that way whatever happens in the future the machine does it all?
Do you also need to anneal cases that are:
Longer than 2.5" with a diameter between 0.5" and 0.625"? Add Large Caliber Kit
Between 1.25" and 2.0" long with a diameter less than 0.5"? Add Small Caliber Kit
Shorter than 2.0" with a diameter between 0.5" and 0.625"? Add Super Short Magnum Kit
oh god thats 516$ CAD with the shipping and upgrades, screw that.
