I sent out some inquires to some friends, it appears one of them was involved in developing it:

The powder was developed by General Dynamics, the largest munitions manufacturer in the world. And when the engineers who put it together first camae 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.[/align]

Blackhorn 209, according to those engineers, produces right at 5% higher velocities than FFFg Triple Seven, with about 10% lower pressures.[/align]

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.[/align][/align]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[/align]
