I have thoughts along that same line Lane. 5744 worked great for me in several old BP rifle calibers until I switched completely to BP. I might have some left in the shop to compare to BH209 when I get some.
I'd be very interrested in what 100gV of 5744 weighs out on the scale :wink:
.
Here ya go Lane, 100 gr by volume of 5744 weighs 98.7 gr by weight. This REALLY surprised me. Keep in mind, 100gr by vol. of BH209 weighs only 67.08 gr. Kinda gives you an idea of how bulky they managed to make this powder.
The only powder I have (or have ever seen) that looks nearly identicle to BH209 is IMR SR4759. Ballisticly, these two powders are EXTREMELY similar. It too is a hollow extruded powder. Oddly, 100 gr by vol of SR4759 weighed 82.3 gr.
One theory could be that they took 5744 and "hollowed it out" like SR4759. This would add the bulk. Making it less dense and increasing the volume. Then "coat" it with something dirty that makes it "smoke."
Of course, I am not a bullestician, just an arm chair quarter back and all this is speculative.
Come on Western... Tell us how you made it!
