I know nothing about sealed nitro propellant, but I HAVE successfully shot black powder from a sealed container - dated May 1903. Not with the gun in my hand, mind, but at a safe distance and from behind a large John Deere tractor.

I've used many kilos of snia gm3, mostly in. 45 acp and then in rifles with cast bullets. There is data available but mostly in Italian, its an Italian powder. IT IS NOT THE SAME AS VECTAN GM3!

Loads for. 45 acp were on a par with bullseye. It meters well and is very clean burning.

As others said, if the can is still sealed it should be ok.

I'm quite amazed that for the sake of about £30 you are willing to risk blowing up your gun or blowing your hand off.

I was given a tub of Unique. I am 99% sure it is alright but I don't know for certain that it has been stored right. I will burn it off and quite happily buy a new tub that I am certain there is no risk with.

What you are born with is supposed to last you a lifetime. Eyes, ears, head, hands etc. Why risk changing that for the sake of a few quid?

I second that. My post was really just to give you an idea of what it is. In reality you don't know where it's been, how it's been stored or if it's been contaminated. There may be a good reason why it didn't get used. Best thing is to spread it over the garden, an expensive fertiliser but better the risk of life changing injuries or death.
