So, apparently Bertram has a US distributor now, and you can order directly from them..
I'll be needing some .45-100 brass in the near future, and it doesn't look like starline is going to get around to making any.
The Bertram site lists .45-120 brass in stick, which I could cut down. The big downside is that it's $4.85 a piece.
Besides the exorbitant price, is there any reason that it won't work?
