Anyone used PP 1200-r to load Grendel? More inside.

Mseric,

Thanks for doing the research!

My best guess -- Both are correct. Hornady and Nosler have access to pressure test equipment, and good communication with the powder manufacturers. As a result, they can do things that we can't with our tools.

We see a similar situation with LeverEvolution. I have been directly advised by Hodgdon ballisticians to not try the powder in chambers they haven't already posted loads for. The rational: the powder doesn't always behave the same going from one chamber to another and can develop high pressures much sooner than expected.

I guess, for the sake of safety and discussion it would be helpful if those that found 10X "dangerous" posted their load data, and all related details that brought them to the "dangerous" conclusion.

Then we could at least compare what Hornady and Nosler list as safe against those that found it unsafe.
