Ok LP, tu ne sembles pas vouloir répondre à ça alors je vais y aller de ma meilleure hypothèse pour te faire bouger.....
Un 2$ là-dessus:
Tu as essayé la BH209
Dis le, j'en suis certain
Est-elle aussi merveilleuse que tout les articles le disent? Vitesse, tu l'as déjà confirmé, mais corrosion? Précision? Propreté?
Joyeux noel à tous

I sent out some inquires to some friends, it appears one of them was involved in developing it:
Quote:
Lee,
The powder was developed by General Dynamics, the largest munitions manufacturer in the world. And when the engineers who put it together first came to me 3 years ago to discuss...they said they could make a new muzzleolaoder powdeer do whatever we decided it had to do. And one of the things immediately brought up was better control of pressures...which would mean a progressive burning powder.
Blackhorn 209, according to those engineers, produces right at 5% higher velocities than FFFg Triple Seven, with about 10% lower pressures.
For reporting on the powder, for the .50 caliber, I've stopped at 110 grains...until more pressure data is availabile. However, in my own shooting, I've gone up to 120 grains to get the 250-grain Barnes TMZ out of my Knight at 2,168 f.p.s. - and still with good (sub 1 1/2 inch) accuracy.
Sabotloader might know who I was talking to, I dont feel free to mention his name with out asking. I am not about to spoil the source that might see about getting me a can to test. Lee

This is getting more interesting as information leaks out. I was told that General Dynamics was on contract with Magkor to make Black Mag'3 about the time the clumping issue came up. A source that I believe is reliable claims that General Dynamics cut some corners in the production causing some problems with the powder resulting in a cut off of the agreement between them and Magkor. Now we see that it might look like General Dynamics may have had an iron in the fire to come out with a competitive powder before they went into the agreement with Magkor. Sure wish I knew all the real information. I suppose it all the information was correct and could be proven it would spawn lawsuits and we would never see either of the powders on the market. I am not saying that this is true I am only saying that it might look that way to some.

David: I think you are correct. I really have had very good results with Black Mag'3 but have constantly been advising them that availability is number one and price is number two. I know getting a new powder on the market for a single product company is a real difficult thing to do but they have to understand that in the beginning. I hope that if this new powder is actually supported by a powder company like Accurate then they may have better distribution capability. It sounds like it is being processed similar to smokeless as the "extruded with a hole in the grain" description sounds like other smokeless powder I have had. As an older single body hunter I have to drop elk fast or they get to where I cannot retrieve them so I really like the possiblity of a fast second shot. Black Mag has allowed my Omega to do that. I have had elk dead on their feet and they still go almost a half mile before stopping. If they get an adrenalin rush they can go forever. (added information) According to a tech at Western the powder is not going to be available until after the Shot Show in February. It is not a rehash of the ascorbic acid based powders. It does require a hot 209 to ignite so the White guys probably won't be interested but Whites will shoot anything you can stuff down the barrel so it doesn't matter. I could not get a price indication. If it is being produced similar to regular smokeless and on the same equipment it is possible that they may keep the price reasonable. As far as distribution they should be in better shape than Magkor as they already have a distribution network for Western/Accurate powders. I am really interested in this one.
