Hello folks,
I just recieved this e-mail from Starline and I thought you would like to know:
Carver,
Our .50-90 case is the closest that I can find. It has a body diameter of .5605” but a rim diameter of about .650”. Overall length is 2.495”. I believe the .45-75 Winchester rim diameter is about .616”.
The .45-75 Winchester is on our “Coming Soon” list along with the other 1876 Winchester chamberings. I do not know when the brass will be available but we will post on our website and send out press releases when it is available.
Thank you,
Hunter Pilant
