PP ball AP putty isn't as powerful as SP AP putty since the NC isn't as nitrated. If using double base SP you also have the added benefit of the NG which no doubt boosts power quite a bit.

Yeah,the nitrocellulose base makes it more powerfull by the nature, the ping pong balls are shitty grade SP and alittle bit of camphor. If in a pinch use the PP method but, i would always go with SP if i had the option.-Pyro

well, i tried the PP method a while back
altho the "general" recipe for AP + PP says to use 30 PP balls,
i only had 6 PP balls - i posted my recipe a little while back...search for it

and i must say i was quite impressed with the reasults
i would say maybe, 30 times more powerful then AP unconfined

I think it's been around for a while, certainly when I first started reading about HE's.

How about NC laquer, which is used in pyro a lot. This thing is about the same as PP but better and cheaper?

I think it's pretyt much the same thing except you get considerably less NC in acetone with the laquer. The PP balls in acetone form a layer of stringy NC goo at the bottom of vessel rather than a solution.

That NC lacquer is useful shit!
All you need to do for a fuse is dip some string in it, and let the string dry. Instant fuse.

CTAP unconfined has not a high VOD!
The maximum VOD reach 5.3km/s!
So be more careful when you say 112km/s...that totaly wrong! You only reach 6-7km/s with NC when confined and in large pipes!
The fastest known explosives have "only" VOD arround 9-10-11km/s and that's twice faster than CTAP!

I posted subject about nc from laquer on may 6th its in miscellaneous after extracting the nc from laquer and letting go hard it only takes a small amount acetone to make it go to a paste in a bout half hour & get quite a bit from liter of laquer which is cheap to buy
