Cast 223 Load Data

[Tramlaw]

I've been casting boolits for a while now. I recently purchased the C225-55-RF Lee 6 cavity mold. I will be using either IMR 3031, 4895, or 4064. I haven't had any luck finding reliable load data. Does anyone here use this mold with these powders? If so could you point me in the right direction. Thanks!

Welcome to the site!
For what it's worth those 3 powders are slower than the ones listed in Lymans 4th (2013) and 46th (1987) edition manuals.
I don't guess you happen to have any Unique or 2400?

To point you in the right direction ??? What are you going to shoot these in and what barrel twist?

Bolt action or a gas operated ?

I have used 4895 / cast in a 12 twist Ar with good results

I did not have much luck with those slow burners and cast boolits in the 223's I have. There are many powders that will work but among the easiest to find on store shelves these days is RE-7. As mentioned above, you didn't say what you will be shooting your CB's in. If your rifle is a bolt or single shot, you have a lot of room to play but if it is a semi-auto you will likely have to keep velocities higher for functioning that action. Welcome to our group by the way!

18grs and move forward.
spend some time culling your boolits and weight sort them into .1gr weights.
