Those are nitrocellulose based powders. They do not work for ejection charges without extreme confinement.

Those are "useless", you should send them to AirFest so I can "dispose" of them for you :-D
My M1 Garand loves IMR 4895, but my ejection charges prefer plain ol BP.
As stated by others, it is a confinement issue.

Those are all rifle powders that you have. The 3031 is the fastest, and 4064 the slowest. They need quite a bit of pressure to burn completely. Personally, I wouldn't try it. You would need fairly robust containment for the charges, and I think the reliability would be iffy at best.

As others have said, Smokeless powder wont generate the pressure or gas volume required for ejection. For fun, take a thimble full of BP and one of smokeless and ignite them. That will be your answer.

Well, as stated, smokeless propellants won't work for ejection. That said, you'll want to hold on to what you have there.
My old can of 3031 still has the price sticker on it... $7.99. Today, that same 1 lb can is $38.
Don't shoot, I've got kids.
