Grendel as a Universal Infantry Cartridge

Bill says it's been measured at 50k psi. Cory says it's actually 10k psi lower. How is that not saying Bill isn't telling the truth?

No that's not what I said.

JASmith was kind enough to run some numbers through quickload.

Per JASmith

My experience with the powder survey utility in QuickLoad is that the numbers generally come out fairly close to the velocities generally reported for safe loads with a particular bullet. A note of caution, however, is that QL results can frequently vary from published pressures by 5,000 psi and velocities by 200 fps when modeling particular loads. Hence QuickLoad is best viewed as a tool for developing insight rather than specifying particular load recipes.

I don't think anyone here doubts Bill A in the least. Those numbers show that the load could have been accomplished at anywhere from a 39ksi to a 50ksi load. This supposts both what I said in this thread and what Bill A has told us.

Back to the Wolf ammo. It appears to have been developed with an ultraconservative load. You'd think in 8 years of development they could have refined their analysis and design, allowing a less conservative choice.

With recent events I wonder if they hadn’t already made a substantial order of powder for the 110gr steel core projectile, and then had to switch the projectile last minute because of the ruling on the 5.45 ammo. Rather than going back to the drawing board, selecting a new projectile, and selecting a powder for the projectile, they may have selected the new projectile based on the powder in hand.
