Fireforming .44-77 brass?

[Distant Thunder]

Thanks, Eric.
It's good of you to help out with advise since you are the responsible for this project! Well in part anyway, there are plenty of enablers around here.
Judging by all the views threads about the .44-77 get there are a good number of other shooters with the itch too. I hope to help them jump in with a push.

I've decided to use the GG bullets I have already cast and sitting here for my fireforming, but those will be the only grease groove bullets this rifle will ever sees. For powder I have several cans of odds and ends leftover from 30 years of shooting these big bore single shot rifles and many years of shooting muzzle loaders. I have more that enough.

Thanks!
