BLACK POWDER
#1
Brick 
Rocketry Friends,

Is anyone else out there having problems finding fffg or ffffg Goex black powder?!?  I'm having a devil of a time finding black powder for ejection charges.  Any tips on finding some good rocketry black powder would be greatly appreciated.

Yes!  Back in January when I built my first DD rocket for my L2 cert flight I called gun shops in 3 nearby States, Dicks, Cabelas, and searched the internet but all I could find was synthetic BP.

Then I found the Maine Powder House Big Grin   Bought 5 lbs of GOEX 4F BP.  If you can manage to put together a group buy for 25 Lbs they ship it free with no HAZMAT fee.

You'll need to FAX (or email with graphic attachment) your driver's license with a 1-page first-time order statement form, but they're great people.  My order was shipping the next day.

I bought a pound from http://www.clydessports.com/ in Linthicum, MD. I signed their book, and they never asked me what it was for. I don't know if they are authorized to ship it.

You have to find a gun shop that sells muzzle-loaders.

Oh, and I think most vendors will keep some in stock at launches, though it is expensive to buy that way. $40 a pound as opposed to $25 at a gun shop.

The present cost for 1 lb of 4FG BP at the Maine Powder House is $17.25. Adding the HAZMAT & shipping charges will bring the per pound cost near $25. But if you can get a group order of at least 25 Lbs it's only $17.25.

If you had the cash, and inclination, you could get 25 lbs and sell-off the excess at $20/lb make a few bucks while helping your rocket buddies save some cash as well.

Personally I wouldn't make a habit of doing this, but would consider doing it one time...

And my assumption would be that it is a controlled substance and illegal to sell without a license. So you might not want to put that in print.

OP, do you know anyone who is into guns and might know where you can look near you?

There is also a rumor that Bass Pro sells it, but you have to ask, and they keep it out of sight. Bass Pro near you?

I've looked everywhere locally (w/in 200 miles)... gun stores, reload suppliers, sporting goods places... no Goex. Here are two more questions ... is 3F or 4F better for rocket ejection charges? Also, is it OK to use non-Goex powders like Hodgdon "triple se7en"... I found some 3F of that brand at Cabelas.

I've been told 3F or 4F BP will work, but my experience (all good) is with using 4F.  In my area Cabelas only stocked synthetic BP which I have been told does not produce an effective ejection charge burst.  Once I heard it was synthetic I did not ask the brand name.

I stopped looking after finding the Maine Powder House, and the 5 lbs will last me - 200+ flights per lb... Rolleyes

I'm not familiar with Cabela's, but if it is real BP and not synthetic, and if it is certified FFF, I think you are good to go. 3F needs to be packed a little tighter than 4F, because it is less refined and the grains are larger.

I totally understand the need for Internet anonymity, but without knowing where you are, it's hard to help further. I can make assumptions all day, but not very useful ones.

If you're in a club, ask around. If you have a vendor at your launches, try that. Any annual gun shows in your area?

Hey guys, I found a source through a fellow rocketry club member. By the way, everyone's telling me that 4fg is the way to go. As long as you're using it for yourself and not selling it, you don't need a license to buy it.
