Re: burn rates
[ QUOTE ]
I have looked at several burn charts but they all seam to be different. Does anybody have a sort of scientific burn chart. I'm looking for something that has time burnt type of information. I would like to know the difference specifically between powders. such as H-1000 ans RE-25

Burn rate charts are very close approximations.
The reason that some powders will swap positions from one chart to another is that the determination of burn rates is not an exact science. Also, because stick and ball powders have different basic designs, they have different advancement rates, which means that at 45Kpsi, "A" will burn faster than "B", but at 55Kpsi, "B" will burn faster than "A".
The good part of all of this confusion is that if two powders exchange places, it's because they are so close in burning rates, as to be just about identical.
