Hello all,
I have searched several forums and the holy google to no avail. I'm looking for a good chart that outlines the difference (if there is one) in loading loose powder substitues and how it compares to real black powder.

My ideal chart would have something like:
(please disregard the BOGUS numbers here, i have no clue what it actually would be)

Brand substitute / # grains = Black Powder / # grains *EDIT! .44 cal with .454 ball loaded*
Bogus Example #1: Pyrodex P / 36 = Goex FFFg / 40
Bogus Example #2: Tripple 7 / 30 = Goex FFFg / 40

Does such a chart exist?

The Hodgdon website has loading data for Pyrodex and T7.

http://www.hodgdon.com/PDF/muzzleloading_manual_2008.pdf?CHECKBOX_1=on

And Goex has this site: http://www.goexpowder.com/load-chart.html

Some members of this forum and others have come up with comparisons; but, there is no site with comparrisons that I know of.

mec has posted many chronograph velocity figures in the past, and I've reposted quite a few of them since, but they can be model specific. And these below don't include any of his .36 or .31 caliber velocities or the data that he's posted along with photos of guns & the other bullets and loads that he's chronographed.

For example:

28 Grain Pyrodex P 966
28 Grain Goex FFFG 795
28 Grain Swiss FFFG 959
35 Grain Swiss FFFG 1089
40 Grains Swiss FFFG 1104
40 Grains Pyrodex P 1125
.454 ball- Uberti 58

Loads in 1860 Army:

28-30 grains with round ball is a very satisfactory load whether you use goex FFFg, pyrodex p or Swiss FFFg. Mine works well with up to 35 grains and will hold 49 grains with considerable compression. At 40 grains, my particular revolver will display hammer blow back and rough functioning with Swiss or Pyrodex.
(all charges thrown from a measure calibrated for goex fffg. The actual weight of Swiss is greater while pyrodex is much lighter and compresses more readily)
Loads 140-141 Grain Ball Velocity Spread/6rounds

It can be kind of odd stuff. I was shooting a .457 ball in my Remington/Uberti and it was spactic at any charge beneath 35 grains. It liked that charge fine:

35 Gr/Vol. H777 1061 28(spread)
A couple of charges worked well with the RamLok Bullet:
RamLok 194 Grain Bullet
30 Gr/Vol. H777 937 30
35 Gr/Vol. H777 1106 33

35gr/vol seems to be the majic number with my ruger old army and .457 balls:
35 Grains Swiss FFFg 1088 90spread 376 ft.lbs.
35 Gr/Vol.H777 1046 89spread ................340
35 Gr/Vol. Pyrodex P 992 88 spread......313
Billy Fiveshooter uses it exclusively in his ultra tight Clements 50 old army conversion and shoots some amazingly small groups.
