I never had any trouble finding them over here in Vernon, I think I bought all they had at the time. Then I also bought some at the gunshow in Kamloops, I'd buy the rifle then worry about the brass. Its a real good cartridge that we have used to take quite afew deer and I shot a moose with it as well.
That might work Paul, I haven't checked into it. I have never had a problem finding 307 brass, although its not that common, I just pick it up when I see it and now probably have 200 brass. They need annealing to keep the splitting down.
