Would that not produce flying pieces of clay 'shrapnel' ?!

I always took the paper-only approach and never had a problem.

well in my opinion its no different to hardend glue , hard glue propelled at high speed could do the same amount of dmg as clay propelled at high speed, and clay has more of a chance of shattering/crumbling when the banger goes off than being propelled as shrapnel , where as glue is hard but flexible & would not shatter/crumble on explosion off the banger, just my opinion , maybe right maybe wrong but seems right to me.. and industrial bangers use clay in theres, ive never seen an industrial firework use glue as a seal.. that must tell you something... not that im saying theres anything wrong with glue, i know nothing about it , but if industrial bangers use clay and not glue, and if clay can shatter like 99% easier than hardend glue could, i think glue would be shrapnel before clay would.. you maybe saying how can glue be shrapnel if it doesnt shatter peices.. well it would be more of a flying bullet than flying shrapenl but its all the same in my opinion...

depends how well milled it is. If you've ball milled it for a few days it should work fine, if not, then yes, chances are tore will be a small report and a flare

Itll be balled milled for quite some time yes.. it still wont produce a good banger? is it because of clay sealing? i thought industry bangers used clay to seal?
