When I once did some searching on the BP vs Pyrodex subject, I found an interesting site which included videos of a series of ground tests of a rocket deployment:

It seems like the key with Pyrodex is to keep it contained while burning for a longer span of time — they had to wrap their plastic ejection canister in 3 layers of electrical tape to get a decent deployment.
Nevertheless, I’m sticking with BP for the foreseeable future. particularly since I’m new to high-power…..I’ve made the trek over to Blunderbuss to get some — as soon as I asked for 4F, the owner said “Rocketeer, eh?”.
75 GRAINS ?? What is that?! One of those Wimpy Girly Guns?! 😯
We have always used 110 grains 8)
And If there aint a big fog bank, after you fire, how do you get any protection from the enemy?
Actually, I shot 100+ grains of Pyrodex and I couldn’t get my gun sighted in. Remington suggested I go a lot lower, and I started at 70 and ended up at 75. VERY accurate. BTW, I looked at my bullets – they are 450 grain — but the 75 grains of Pyrodex was accurate. It is counterintuitive to cut back on Pyrodex, but that is what I did and it made a lot of difference.
I use 777 in 50 grain pre cast pellets for my inline (junk, don’t light well), 4F in my pistol and KY Long rifle, Pyrex in my Thompsons. I have a lot of powders sitting in field boxes. 😀 I haven’t been brave enough to try and shoot my real ones – 3 band Enfield & Percussion cap musket.
Anyway. We digress.
Did you get what you wanted yet Scott????? BAHAHAHAHA
That you are using?
Thanks for this tip. I’m going to test it out. I have the Quickburst e-matches made from their kit. Curious to see if these will light up Pyrodex.
We are Good to Go with our scheduled and approved launch on Saturday April 5th and Sunday April 6th, from the North Site, subject to change – Mostly cloudy and High Winds predicted. Range and waiver should be active by 9AM on Saturday. The Pawnee National Grassland remains fragile and dry, so extra precautions are in order. Please stay on the authorized roads and please don’t park more than 100’ off the road at the flight line.
