I don't see how you managed to get even the fastest BP to turn a small rocket into a firecracker..You used meal right? And pressed the BP into the
rocket with a strong clay plug holding then end in? Core burner or end burner? I like core burners personally, but there are advantages to the other
types. A little FFFa can be added, but if you have good meal there is certainly no need..maybe your IR penetrated..add a little graphite powder next
time, it solves any IR problems and catalyzes the reaction (or so I've heard..). Also I know many experienced pyros use binder when making their
rockets, but if you do make sure to add a stochiometric amount of oxidizer afterwords. I use KClO4 to balance the binder, but make sure not to add
any more sensitive oxidizers than KNO3 pre-milling. I use 4.2% dextrin, 4.2% Parlon and 8.3% KClO4 and wet with a 50-50 acetone water mix--its
probably a bit excessive, but it doesn't slow down the BP, and I get very hard grains. Gee, its been awhile since I've done any pyro, I miss it. /:
