Lightning shell classification

Thanks!
But "strung"? - Wrapped tightly with string?

You never come across a string bound maroon? Someone once showed me a ~40 year old Standard string bound maroon shell in their store. A collectors item.

The latter-day equivalent of the 'Panda Pops' bottle...

Also, if you've helped Demex with his flour bombs at the Woodman you may have seen him emptying black powder out of 16oz strung bound ground maroons. HFM do them.

Sorry Andy i`ll rephrase that!!

What i meant by:



Basically a canister full of powder, much like a small shell canister. Then it is Spiked - wrapped tightly all the way round (with String!) to increase the pressure on the case making the explosion more violent as it takes the gases longer to escape. This creates far more lifting force to get the big shells up there.



Was that the technical name for the string wrapping is Spiking. So they tightly wrap string all the way round the case. Much like as just mentioned above on old fashioned ground maroon.

The Maltese are the best for demonstrations of strung bound shells. There was also a documentary with a very young looking Mark Lancaster actually doing a strung bound shell some years ago, just after he left the army !

The Maltese have some interesting ways of making shells, some of which may not be UK classifiable! The sometimes use a nominally small lift with a shock absorber of corrugated card to push very long shells out of mortars.

But back on OP, I have heard that big salutes are going to be 1.1 when cad paperworked in the future. Wrt stuff in stores .........???

any shell >25% flash will default to 1.1G already

Ahh i'm glad someone beat me to explaining, damn internet going down!

Yeah it's basically a canister surrounded by string to increase the pressure but the lift is seperated from the shell with 'wadding' so it doesn't tear the shell apart too. The Americans like to string their salutes too.
