I don't plan to sit down and fireform 300 cases in one session, but if the rifle works out as I hope, and it will, I'll need 200 cases minimum to shoot the matches I will eventually shoot with it.
Don,
Yes, you are right about this as I knew you would be. I was in part thinking out loud when I wrote that and also wanting to confirm my thinking is on track. Tapping into the vast experiences of other shooters here is a good thing and often reveals something I hadn't come up with on my own. Especially with a cartridge which is a deviation from the usual straight case.
Besides it just seems this forum needs a little KICK start once in awhile.

A friendly discussion of ideas is a great winter sport!
I'm probably go to go with those GG bullets, they are of any other use to me, and some of that orphan powder. That's about the least amount of effort and expense I can think of that will still get the job done well the first time. Thanks!
