Paper Patched 45-75 ... 20th Century Version
« on: December 20, 2007, 02:35:23 PM »
Back in 1878, there was mention in a Winchester catalog, that they made a loaded PP round for the '76 Winchester 45-75.  No one has ever seen this round though.  So, I made my own! ... Paper Patched 45-75

John Boy. Ive been thinking about doing the same thing for my 45/70. Ive never pp before, just reading up on all the details right now. Your pp bullet was .454. wouldnt you want it to be 458 ? & if not whynot. Like I said Im in the reading stage of paper patching. Im thinking about using A hornady sst 250grain .451 pp it to .458   Jay
I dont care what gun Im using as long as Im hunting

Jay, the adjustable mold that I have casts a bullet at 0.446.  Rule of Thumb is the naked bullet be 0.004 to 0.006 smaller than the bore diameter so when it is wrapped, the patched bullet is 0.001 to 0.002 larger than the bore diameter of the rifle when shooting black powder.  For smokeless, the unwrapped (naked) bullet should be equal to or 0.0005 greater than the bore diameter

This 45-75 (not 45-70) rifle has a bore diameter of 0.451.  The 2 wraps of 9# Vellum gives me a wrapped bullet of 0.053

Fernie, as mentioned for the 45-75 experiment, the alloy used was 1:11.  The alloy ratio was on an old box of Sharps Long Range PP bullets.
As for the casting temperature, it can vary.  Every mold is like a woman - likes something different.  This particular mold likes 710-730 degrees Fahrenheit

As I also stated - "How do they shoot?  Have no idea but will find out next time at the range."  In the meantime, Merry Christmas
Regards
John Boy
