If the manufacturer of the powder publishes their numbers using the same components as I, my expectation is a similar outcome.

I run my loads across a chrono, and get very small sd’s.
So I know I’m precise in my practices.

I trust the powder manufacturers research on pressure.
It’s just up to me to be consistent on my end.

Now that there are way fewer options out there, the process is actually easier.

Out there doing it best I can.
