40-70 SS loads

The problem with making brass for the .40-70 is that there are so many variances in the rim thicknesses and even the diameters. The diameter differences are not as critical as the thickness is.
There are differences between the Shiloh and C-Sharps enough that it creates a head space problem shortening case life. Then the difference between the originals like the Hepburn, Maynard, Ballards and others. The .40-70 was a popular chambering but there where no standards back then between manufactures and it still has not changed today by the differences in the rim recess.
I can understand why they hesitate making brass for the .40-70. Bertram does make .40-70 cases with the correct headstamp and it fits my Shiloh but case life is very short. Or was when I first got my rifle.
