Magnesium in APCP propellent binder is much safer then putting a bag of Magnesium in a magazine.

Thank you!

I don't think it matters if it contains magnesium, aluminum, or any other kinds of powdered metals. The ingredients are kind of irrelevant. It is APCP and the fire hazards associated with APCP and what it takes to safely store APCP, is what is important, Those hazards are going to be the same no matter what the metals are used in the APCP.
Worrying about the ingredients while storing APCP is kind of like worrying about if gasoline has Mobile Synergy, Sinclair Dinocare, or Chevron Techron additives in it when you store it. It doesn't really matter, it's gasoline.

I'm new to CTI, just wanted to try something different. I just received a 29mm 5G H194 Red Lightning, dated 8/27/15. Or nearly 9 years old. Old AT Redlines can be a bit tough to light, but the biggest issue on old AT Redlines is that something happens to the delay grain. Burns shorter, I've heard. So...

1. Is there likely a problem getting this Red Lightning to ignite?

2. What about the delay grain?

TIA,

Hans."

1. No problems at all lighting red propellants
2. if you're worried use a altimeter. I've flown much older stuff, however.
