PhilOhio,

Yes, I mean the chamber mouth throats. I have not received the gun yet, and want to get some lead bullets on order from Montana Bullet Works. I am planning on the Lyman 429421 Keith bullet of course, and was unsure what size works best in these old guns. So I should go with .429"?

I am planning on using Unique, and want something with more power than a .44 Special, but not too hot, don't want to knock the old girl out of time. I have read that 9-10gr of Unique works well.
