Anyone encounter the 303 Savage (NOT the 303 British) in an improved configuration?

I've been looking for data on it.

Thanks!

I guess this means you have one, I can't imagine anyone wanting to build one nowadays. I can't help with load data but I would have thought that 30-30 Imp data might be easier to find & would provide a reasonable starting point. Ammoguide shows the 303 Sav as being slightly smaller in capacity as against the 30-30. 46gr water to 44.4, the 30 Rem lists at 44.8 gr so would also be a possiblity for start loads.
