This is something that I posted over on another forum back on 2-7-09, I just don't feel like re-typing the whole thing. I still feel the same about the Black Mag'. You can get more shots out of two 10oz jugs of BH209 than you can out of three 10oz jugs of BM if the new XP is the same density as the BM'3.
"Black Magic, better known as Black Mag, Black Mag' 2, Black Mag' 3, and now the newest version Black Mag' XP is a very clean burning powder. This burns a lot cleaner than 777 or Pyrodex, but the newest version priced itself on a road to going out of business. MDM (Millenium Designed Muzzleloaders) is marketing the Black Mag (Magkor) powders in 10 oz containers, Lightning Loads, and in their Thunder Charge powder/bullet combinations. They are pricing themselves along side of Blackhorn 209 10 oz containers, but what they fail to see is that their powder is much more dense. So basically you are going to have to buy 3 containers of Black Mag' to equal 2 containers of Blackhorn 209.
Black Powder Substitutes are sold by WEIGHT, but for our purposes are measured by VOLUME equivelants. Not all powders WEIGH the same for VOLUME Equivelant charges. See below.
Example 1:
10 oz BM'3 = 4375 grains WEIGHT
100 grains VOLUME = 105 grains WEIGHT (1.05 VOLUME to WEIGHT multiplier)
4375 grains WEIGHT / 105 grains WEIGHT (100 grains VOLUME) = 41.66 Charges per container.
Example 2:
10 oz Blackhorn 209 = 4375 grains WEIGHT
100 grains VOLUME = 70 grains WEIGHT (0.70 VOLUME to WEIGHT multiplier)
4375 grains WEIGHT / 70 grains WEIGHT (100 grains VOLUME) = 62.50 Charges per container.
You can use the above multipliers to figure out how many charges per container you would have for your typical load.
Black Mag Example: If you typically use a 80 grain VOLUME charge of powder, 80 grains VOLUME x 1.05 (multiplier) = 84 grains WEIGHT. 10 oz (4375 grains WEIGHT) / 84 grains WEIGHT (80 grains VOLUME) = 52.08 (80 grain VOLUME charges per container)
Blackhorn 209 Example: 80 grains VOLUME x 0.70 (multiplier) = 56 grains WEIGHT. 10 oz (4375 grains WEIGHT) / 56 grains WEIGHT (80 grains VOLUME) = 78.125 (80 grains VOLUME charges per container)

The ONLY thing Black Mag' 3 has on Blackhorn 209 is it's ability to be used in #11 ignition rifles. Blackhorn 209 needs a hot 209 primer, but offers several other advantages over Black Mag', price per shot and availability to name a couple. Black Mag' has never been able to get the product on the shelves in more than a few choice locations. They had a deal with Cabelas at one time but screwed that up and Cabelas gave 'em the boot.
Long story short, Black Magic is a clean burning powder, price and distribution are not on their side. I predict, they were too late for the game now that Blackhorn 209 is out there. Western Powders has far better distribution than Magkor, Blackhorn 209 is the best BP Substitute to date IMO, you just need a hot 209 primer to set her off."
Check out their "Lightning Loads". Even if they don't have to pay the hazmat fee, the standard loads (100 gr equiv) will cost you $18.90 for 5, or $3.78 per load, and that is just powder. The magnum loads (150 gr equiv) will cost you $21.90 for 5, or $4.38 per load. Of course the more you buy, the pricer per load will go down because of the one shipping charge, but 30 standard loads will still cost you $68.65 or $2.29 per load. The magnum loads will cost you $86.65 for 30, or $2.89 per load.
Six 10 oz jugs of BM will cost you $208.65 per their website, that will yield you 249.96 100gr VOLUME charges. That is over 83 cents per shot.

Six 10 oz jugs of BH209 will yield you 375 100gr VOLUME charges, 1/3 more for less money. $26.65 per jug at Powder Valley x 6 jugs = $159.90 + say $10 for shipping + $20 HAZMAT = $189.90. Just under 51 cents per shot.
Click on "Powders", then click "Accurate", BH209 is on the top line.
