Powder burn rate charts?
I have three charts with 131-173 powders listed.
The question I have is:
Do any of the posters / readers here have a source of good reference material that can be down loaded for burn rates. One that is trusted to be accurate by many users.
The charts that I have don't agree with each other at all and list powders in different orders of burn rate by several positions. I understand that powders change / evolve over time but what is the latest source of information out there.
I have found that the chart on http://www.reloadbench.com/burn.html seems to be more consistent with my manuals selection of powders.
Any comments or information will be appreciated.
I use the Hodgdon chart on their web site. Since they distribute IMR and Winchester I figure they have an advantage.
Just a heads up that burn rates are relative, not absolute. What that means is that in one chambering powder A will burn faster than powder B, and in another chambering powder B will burn faster than powder A.
I consider powder burn rate charts to be interesting, but useless as a source to try a powder that hasn't been tested in a pressure gun for a given chambering.
I was reading your post and took a look at reloadbench.com
What a great website!
