SAAMI specs on the 44 Magnum is STILL 40,000 CUP or 36,000 PSI depending on the type of pressure gun. PERIOD.
I ain’t buying that. I shot those 60’s and early 70’s loads and that wer 1400 FPS plus. I chronographed some early 70 Remington JHP recently that I had saved and they were 1400 FOS in my M 29. The speeds from factory Ammo dropped when they switched over. If they were the same then the speed would not have dropped.
