PP mould for .45/70

[Kurt]

Ok. Now that you say for a hunting bullet.
My choice for hunting either the 45-475p and the 45-500P would be my choice just the way they are specked out with his drawings.
Here is why I like them as they are specked out. I like a PP bullet patched to groove for hunting. The bullets with that diameter would not quite be ideal for a .45-70 using them for a groove diameter because it would cut down on the powder charge some but for the 2.4 or longer cases in my opinion would make a great bullet.
I like the PP bullet patched to groove in the longer cases for a fast follow up shot if needed. The groove diameter PP bullet can be seated off the throat a few thousands so the fouling in the throat is not a problem that a bore diameter bullet can have.
With a groove diameter bullet patched to .458" pretty much fills the chamber and this helps seal the gas blow by faster then a PP bullet that is patched under bore diameter with in mind that it would chamber in a fouled bore but there is a large gap that it has to seal when it upsets when the charge goes off. Yes the wad stack is supposed to help, but just think for a minute. When you prep your brass for a bore diameter bullet used for hunting you size your case down more to hold that bullet so it don't fall out you might even use a long taper crimp or one of those bushing dies to size your neck down more to hold the bullet. This also sizes the wad down and lets gas get by to cut the patch and the bullet. A groove diameter bullet that is seated at a proper distance off the lands lets you shoot dirty and problems I mentioned wont happen.
Also you can weather proof the patch so you can carry it in a cartridge belt and they can be used in a repeating lever rifle.
The biggest advantage using a groove diameter bullet is the ability to shoot more shots with out using fouling control when you properly seat that bullet in the case. The disadvantage is loss of powder if that is an issue.
A flat point is a very accurate bullet in these powder rifles. As well as a groove diameter patched bullet.

Just my way and it works for me. I don't get locked into doing things just one way.
