[QUOTE="MagnumManiac, post: 2809173, member: 10755"] One problem with all of this is that no company making powder has a standard to base their results off of. Instead of using calorimeter tests these days, due to cost, most are using pressure predictions, which is incorrect as far as I see. Having my own pressure trace, I see quite often that due to the absence of using an average instead of actual max pressure, which is what SAAMI does now, the pressures on factory ammo is way lower than what it used to be, and reloading manuals are the same. I would like to know how you come across this BA number, because if this is a heat number, then it is meaningless. The other problem is, you don’t know the volume of powder tested, so this is also flawed. Cheers. [/QUOTE]
