@poofthe using loading data for a 180grain Spire point, for the Hornady 150grain Spire Interlock, Im possibly getting around 44,000psi. According to the Lee manual this is the low end of the recipe. The primer is not flatten, but not plump...that indicates a standard safe load to use...though the rifle can handle much higher pressures, not to exceed 50,000, just like the 30Gov't.

I make them. Hornady 150gr. Interlocks, PPU or norma brass. You can get that stuff from grafs and sons or midwayusa websites.

yes with out them my grandfather would not be dead

@poofthe Ill make a note to not hire you as my metallic cartridge reloading accountant. If you are spending that much per cartridge then you are overpaying. Each cartridge I roll-up costs me 0.74cents after including the price of a case...0.33 if the case was not counted.
