thats a good idea for a case, i would have never thought of that, and what are you plugging it with??

Which the aluminum tape or the register tape core? I'll assume aluminum tape considering you've been in this thread since I mentioned the cores earlier.

I've just been ram rodding a wad of tissue in there and then dropping some hot glue inside and on the outer surface, then I place a bit of the aluminum tape over the end and cut it out so it folds neatly over the end...into a kinda union jack shape

then another layer around the cylinder, then another bit of the aluminum tape/union jack thing..

I've only done two layers of aluminum tape thick...it's pretty resilient so making them too thick would, I assume, just cause the wadding to blow or it would just fly away like a rocket. (this happened to one I made too small to hold a decent charge of FP)

So just for random little "kicks and giggles" a medicine container would work pretty well?

yah go for it, it should work well, and if you fill it with a high explosive it will make a pretty good bang

Forgive me if I missed the post, but has anyone talked about casing sizes that seem close to perfect? By perfect, I mean, while using 70/30 FP, is there a widely favored shell size, like 1"OD, 1/8" wall, 2.5 inches long (spiral, what I have now), or is that too big (wasting powder)? It seems that the harder I look, the more confusing it gets...I've held M-80's that seem to have lots of airspace, like half full, but I've also heard that the more you tamp, the better the boom.
Is there a sticky somewhere that can help answer this? Also, is there a certain black powder (retail) that can make a pretty good boom in the above casing?
Thanks.
P.S. Please guys, I understand there is no such thing as a "perfect cracker", and it will probably take a lot of trial & error, so tell me to "Piss up a rope" if this request appears "lazy"

Thats not a stupid post at all, I'm just not quite sure how to answer it.

With the plastic roll for the coupons and such that someone posted before,You could probably put the material inside of the roll itself.(duh) Then for a more dangerous version put ball bearings in the little notches that circle around the material.(Just a idea)

Ball Bearings?? please don't "poop" on my question. I just want a good kaboom......you must have your neighbors in constant fear for their lives with ideas like that, who puts BB's in salutes??? and why??????????

Gawd we are in trouble.......

Question about paper tubes. What's the best way to plug them? I have paper end plugs, should scoring and gluing do the trick? Any help is appreciated. Thank you.

yah that should work
