I am particularly impressed with how slow burning it is in the open. In your video it looked like a white star comp. Does that stuff seriously function as flash in a salute? I have never experimented with it but it seems that it would give less of a report than the same cavity filled with BP.
This comp gives an excellent report when contained. I find the report to be just as loud as standard 70:30, and some people think the pressure wave is greater. Can't say, one way or another, but it certainly goes boom. Loudly.
Nice video Kevin. Are you granulating it so you can store it, or just for ease of loading devices?
While it certainly burns slowly, it is an extremely hot burn. Not something you'd want climbing up your arms.
How do you compare it to using blue aluminum? Not as safe, but more reliable?
Thanks again for the detailed article, I still haven't used this stuff, but do have some TPA.
Dan, I granulate it mostly so I can fill bottom shots solidly and not have the comp settle. An added benefit is the reduced dust - this year when I made my bottom shots, I went through 6 kilos of flash. It was nice and easy when it came time to clean up. Finally, when granulated the comp burns more aggressively in devices but burns slower in the open. I can't explain why - it seems counter-intuitive.
I agree I wouldn't want this stuff going up in my face, but I wouldn't want star comp - or any other comp - to do so. To my mind the big benefit is that it is far less likely to initiate at all - the TPA seriously desensitizes the comp. I can't compare it to blue aluminum, as I've never used it.
