I'll probably shoot a couple more of them tonight, C6 to green and red ones, hopefully it'll be less windy as last time, as you can see the comets flew rather poorly as in not straight enough.
Very well done. I like best the third double shot, very nice red and tails. Is your cavity tool home-made? Do you have prefire vids? I ask because I still have trouble with the structural integrity of comets with inserts, so it would be nice to see how it's done perfectly ;o).
Yup, the tool is homemade, the dimensions of the finished comets are as follows, the lenght of the comet is 20mm and 17mm diameter, the cavity is 8mm deep and 9mm Dia. I find that ramming these comets is the only way to go apart from pressing which is nerve wrecking to do unless they are BIG, anyway, a hit or two with a 500g plastic hammer will do the job just fine. When they are dry i prepare a the composition (in this case Mg based colours) and wet it with NC lacquerand press it in the cavity.
When this is also dry (very quickly), i wrap the comets in 2 turns of gummed tape, make sure there are no spaces between the paper and comet, the side with the cavity has a little extra paper so it can be folded down to protects the coloured composition from ignition, when dry, fire em and enjoy :)
The red was Blessers magnesium red, very bright red. The comp is 55% Sr(NO3)2, 28% Magnesium (100mesh) and 17% PVC powder, really simple, although it is quite expensive because of the magnesium but for such small comets it's the best :)
omg great comets, 5 stars

Well done. I'll have to give some cavity comets a try.

Give em a try, they're really cool :)

Thanks for the particular description and suggestions, that should do the trick.

Very nice Work.
Did you use Strontium nitrate or the carbonate for your comp? The colour is a really nice deep red, so i think you use a chlorate too. 5/5
