Brent-
Thanks for the comments.
I was on the fence with the Dixie mould service, and ended up just making it happen out of stock in the machine shop one night while I was out there pondering modifying another mould.
On your Dixie mould -
Did you request a mould for .630" balls? If so, how close to the number are they, and how round does your mould cast them?
The as-cast size was my main concern, as I didn't want to end up with undersize balls for this cartridge rifle. There's no making it up with a patch here.
I think I've asked this before, but please freshen me up on this.
How does your Lang shoot? What's the charge? Do you know the manufacture date?
