Does pyrodex powder get old? I have had some in it's original can for 8 years. I decided to go out and do some muzzleloader hunting this year but I am just questioning the age of the powder. It is cheap enough to jus replace it but I would like to use this is if possible. I will be using non inline rifle so a percussion cap will have to ignite this old powder. I don't want to have to try it out, mainly if it doesn't fire then I have use a bullet puller. Anyway I thought I would ask here to see if has some pyrodex that has some age on it and still goes boom!
