In reading some of the posts below, "reloader 22" etc. I want to know who has the most current burning rate chart published. There have been a number of new powders debuted in the last year or so, and it is useful to know whats out there.

danev2,

Welcome to the forum.

The short answer is no one!

If you look at several tables from different sources, you will find that a lot of the powders seem to play musical chairs with their position.

Check the FAQs page on our site, there is a burning rate which we compiled from several sources.

You might like to bear in mind that this is only an indication of their respective buning rate.

Powder burn charts seem to be very general, at best. Even between calibers, powders will flip positions on the chart...particularly in the midrange of the chart.

With that, the one offered on Hornady's site seems to be kept up to date.

Burn rates appear to depend on the cartridge and the pressures it operates at. No chart is gospel, only a very rough guideline.

To all concerned __

I have ceased to use "burning rate" as an indicator of what I can expect from a gunpowder. Winchester-Olin also no longer lists "burning rate" in its' literature. The author of "Quickload" also disputes the validity of "burning rate".

In lieu of that, using real published data, I have compiled tables and charts listing Energy per grain weight (E/gr.) and Velocity per grain weight (V/gr.) for all of the gunpowders, bullets/cartridges, and calibers where sufficient data were available to do so.

A formidable task to be sure. But it gave me something to do while healing, and when ambient conditions precluded loading or shooting.

Nothing more than personal preference and opinions.

Good shooting.

Post it on the board. A link to it anyway. Don't keep us all in suspense.

Aren't explosives and propellants rated in linear burn rate, as in feet/sec? Seem to have seen a list, somewhere, to that effect? FWIW, Dutch.

Thanks for asking. It is an interesting subject. However, the amount of data I've collected is more than just a little bit extensive. For example: There are over 600 data points for IMR 4895 alone, accumulated from every source I could access; manuals, books, web sites, magazines, etc., then compounded into something useful like specifics for bullet weights and calibers.

Secondly, being computer stupid (not just illiterate - really stupid), I have no idea how to boil it all down to something suitable for posting on the board. Sorry 'bout that.

The feet per second numbers given for explosives are supposed to be the rate of expansion of the gas "bubble" in open air; derived from an abstract test. I'm no expert in the matter, so don't take that for gospel.

Good shooting.

What format do you have it in? If it's in MS Excell or some other spreadsheet I'm sure we could find someone who could reduce it or graph it. Send it to me and I'll see what I can do with it. I'm pretty sure Saeed could findd a place to post the finished listing on this website. Not intending to speak for him, but it would be beneficial enough to be a logical addition.

Forgot. I've been pulling my hair out over these charts (trying to place H322 while using the VV and Hodgdon charts will do this to you!).

The most useful burn rate listing I have found is the Nosler manual, which lists the powders in order of burn rate in each specific cartridge. It does not have all the relevant powders, but at least the ones they list are in the right order for what I'm trying to accomplish. HTH, Dutch.
