It has been gnawing at me that Dillon, at least in their newest Blue Press, still does not offer a caliber conversion kit for the 550B or the 650XL.

So I called them today.

I'll be darned. Turns out that they DO.

It is a .223 kit with one of two different powder funnels depending on whether you want to load jacket bullets or lead/plated.

If you already have a .223 caliber conversion kit and 300BLK dies, all you need to buy is the appropriate powder funnel, which ARE available individually.

Oh, and if you happen to use a optional case feeder you will want to order the "small rifle" plate.

i didn't order the plate because I have not yet decided whether to use the 550B (no case feeder) or the 650XL.

But I will do my best to remember to post the part numbers for the two funnels as soon as they get here.
