That's kind of my point. It's all just a guess as to what the pressure actually is.
If Buffalo Bore has access to "special powders not available to reloaders," wouldn't Winchester, Remington, Aguila, PMC, and all the other manufacturers have access to these "special" powders?
And, if they do-why aren't THEY producing these "super loads" that BB produces?
It doesn't add up.
