I see that Starline is offering .348 Winchester brass now. That at least gives us a source for forming .45-75 again. The .45-75 brass I have now was made from Winchester .348 brass and it works very well in the original 1876 rifles I have owned.
I looked through all the boxes in my garage today and found 30 of the formed .45-75 made from .348 Winchester brass as previously sold by Buffalo Arms. I guess that will have to do for me until/if another source becomes available .
Doing a google search I turned up this supplier. Etsy? Looks like these are being formed from Starline .50-90 cases. I have no idea the quality or how they work through the action. Who wants to be the "crash test dummie" and order some?https://www.etsy.com/listing/565628034/4575-winchester-center-fire-quantity-20
