KP bursting charge

[Liftanddeafen]

I normally use MCRH but with a petal shell I heard you use KP. Do I need a booster and is it alright if I put the KP on to rice hulls. Or do I have to granulate it?

I never use KP on hulls, just MCRH and a booster, when space between petals is limited I coat smaller stuff.

It's ill-advised to add a booster to KP type bursting charges. They're not nearly as forgiving as BP bursts. Turning your shells into salutes is way too easy, and really doesn't offer much of a benefit. You can tune KP bursts by adjusting the amount of pasted layers.

 

It's perfectly fine to coat it onto rice hulls.

 

KP really doesn't work well for overly small or overly large shells 4-6" is generally sort of the sweet spot in my experience.

I second Mumbles about not using booster when shell breaking with KP, since it may cause too hard break and stars blew blind. I have used KP on Grass seed 1:4 ratio for bursting 3-4" shells and it worked pretty good. KP is generally slow burning composition, but then it's confined it is very powerfull, so pasting has to be done. Now I choose to use MCRH 1:4 + flash booster just because it cheaper and gives good results as well. You can granulate KP, but you will need more KP and shell weight is going to be bigger.

Hello, thank you for you're opinions. I never made it before and just heard that it's better for when making petal shells. I've done a few petal shells but only in small shells and I thought the burst differed as the shell increases in size.

Mumbles, I recently made 25 2" shells and used KP coated rice hulls 7:1 as burst charge and they worked great. the shells had 4 layers of gummed paper tape. seems you were right about tunning KP adjusting the pasted layers.

Now I'm gonna go ahead and paint myself the pyronoob on this one and ask if I can get a definition of the acronyms being thrown around in this thread.Please?

Starting with KP? MCRH?

 

The last part of the latter acronym is rice hulls, I think.

 

But what the KP and the MC stands for I haven't the foggiest.

 

Anyone?

[OldMarine]

KP means potassium perchlorate burst charge and MCRH means Meal (mill dust) Coated Rice Hulls.

I keep the KP for gerb prime because many have ammonium perchlorate as the main oxidizer and prime with potassium nitrate turns the whole shebang into goo.

Question , I have KP & AL areial report , can I add Strontium Nitrate to make it a red flash and if so how much ?

[Mumbles]

First off, that has nothing to do with the topic at hand.

 

Secondly, not really. It might tint it, but it will be far from actually red.

The types of flash that give a colour generally include a chlorine donor of some sort even if it's just in the oxidizer. Becuase red is quite an easy colour to achieve you may get some result but not much. If you have KClO3 then give This a try, if not use what you have but it's unlikely to succeed.
