Providence Tool Co. Peabody

[Kurt]

I just looked that company up and http://www.providencetoolcompanyllc.com/rifles/ it's not that far from me, about three hours.
The problem with the old Peabody calibers is to get a case of the original dimensions. Maybe RMC ? I always thought the large diameter short bottle necked cases they chambered like the .40-90 or the .44-95 if the powder burn would be more efficient in that chamber and if this would improve the accuracy?????
