looking for a powder burn rate comparison chart
« on: October 15, 2003, 05:55:39 AM »
That includes not only smokeless rifle and pistol powders, but also has both shotgun and black powder in the same chart. I've done searches on Google and have only come up with them seperately. None were combined.

Thanks.

powder burning rates

You are not likely to find powder burning rate charts that combine rifle, pistol, shotgun, and blackpowder together.

The reason is simple:  powder burning rate is determined by not only chemical composition, granula size, shape, form, but also the operating pressures that powder is used in.

Rifle, pistol, magnum pistol, shotgun, and blackpowder pressures all operate within such wide variations of conditions that it's not usefule or practical to combine them in one burning rate chart.

Go to: http://www.reloadammo.com/  MD Smith has a comparison chart.  Does not include black powder (BP is an explosive, smokelss burns with great vigor).

I understand what the both of you are saying about the differences in composition, operating pressures, etc. But I was just wondering where, if at all, black powder falls anywhere into the charts. Especially on the slow end. It was just a thought.  
Thanks.

Black powders' characteristics are so different from smokeless that there truly is no parallel relationship therefore it will not 'fit' into a burn rate chart.  A better explanation of your plans or thoughts might ellicit more specific assistance.

I was looking at pressures of pistol and shotgun powders in comparison to black powder.
For instance in a .410 shotgun shell with a slug or shot column, in comparison to an equally weighted bullet fired from a black powder rifle. Average pressures in a .410 are about 1050 to 1300. So it would seem that the same would result in a muzzleloader using roughly the same powder charges.

I know there is a difference, and most people are going to say how dangerous it would be. But was just thinking out loud, and after all, I was one of the first kids on my block with a Weatherby 30-378 when there was very little reloading data available and even the factory wasn't selling complete bullets. I didn't blow myself up with that.  I am also about 90% finished developing a wildcat cartridge of my own. It's a 6.5 X 68R necked down to 6MM. I've got a 100 gr. nosler Bal Tip doing in excess of 3600 fps with absolutely no signs of over pressure, and still intend to get it moving faster. Right now it's devastating on white tails and anything else it's hit. With this under my belt, plus a lot more, I figure I'de survive some experimenting with this also. But I most likely won't do anything with it till next summer, if at all, as bow hunting season for deer is here and I'm outta here. LOL

BTW, I have an Encore MZ loader in .45 cal and as we know, it is one of the strongest BP actions there is.
Thanks for any and all replies. Also any ideas that may help. Other than stay away from it.

The Ramshot Reloading Manual III (free at dealers) has about the most complete burn rate chart I've come across. It includes a lot of discontinued powders for comparison. No black.

Just a thought - POSSIBLY a rough comparison between black and some smokeless could be made using shotgun load data that specifies dram equivalent loads with smokeless powder. Never tried it, no reason to. As I said, just a thought.

About the only correlation, if you can call it that, between black and smokeless that I can come up with is that fast black powder likes small bores while fast smokeless likes small cases therefore slow black for big bores and slow smokeless for big cases.  In your shotshell example the relationships are opposites in that when using smokeless the smaller bores use the slower powders and the larger ones the faster powders.  Using black in the shotshell, you would use the faster (3F) in the small bores and the slower (2F & 1F) in the bigger bores.  In your 45 Encore you could use 50 to about 85gr of 3F.  To gain more velocity, and probably accuracy, you could go on up to about 100-120gr with 2F.  Hope that helped rather than hurt.  BOL.

Here's another comparison for you, but not Black Powder.

http://www.geocities.com/CapitolHill/Lobby/1221/powders.htm , you might try this site.   It has the comparative burn rates of smokeless powders.  I find it very useful for working up wildcat loads.   Don

Mr. Ricciardelli's list has powders that I believe are European.
