There's a different powder. It looks similar to #9 though. How do you ID them since they are so close?
No. 9 is more like like flattened balls and much much finer.
This powder is more the shape of discs, like hockey pucks on a minute scale. A lot of Alliant's powders (Unique, Blue Dot, Power Pistol, Bullseye, 2400, STEEL,...) have that same general shape, varying by thickness and diameter.
I placed some Power Pistol along side to compare and I could not tell them apart from each other. The only other in your list I don't have on hand is 2400 I have worked with it in the past & Steel and I haven't worked with it so I can coment on that one, so I have now way of knowing if it would actually fit the profile by weight to velocity yield.
This photo is one I took with my camera from my computer screen while at Alliant's website one day some time ago. They don't seem to show powder pics anymore, or, I simply can't find where they have them on the website. Either way, this was the best I could contribute in regard to 2400.

After double checking I guess I have a pic of Alliant Steel too; :-[

It's not 2400. It would take 14+ grains to move a 165 close to 1300 FPS. 9.6 grains would be rather anemic. I have some 2400, if a pic is still needed.
9.6 grains of Power Pistol would be more realistic, in all respects.
Yes 2400 is like I remember it as thicker cut flakes than Blue Dot but the excruded diameter is between PP & BD if I can recall.
Steel has a larger flake thinner simular to that of 800X.
Thanks for posting pictures they help improve the ID process... 8)
I tend to agree with the call of power pistol. Good economical powder, fits the velocity profile and visually identical.
Your Welcome The_Shadow. I try to be helpful when I can.
sqlbullet; I'm kind of thinking it almost much be Power Pistol at this point. The main reason I say that is, if it isn't Power Pistol then what other possibility is still out there based on what we know so far? I can't think of one. Is it even possible for Unique to push a 165gr slug to 1300fps from ~4.5" of barrel? It sure as heck isn't Bullseye.
I'm putting these in the sheet. For sure Power Pistol?
I don't see Unique making that velocity without big open mouthed, my fingers hurt, I need new grips sized smiles.
Like I said in another thread, you are only 100% sure when the powder is in the can, but this looks like and fits the ballistics profile of Power Pistol.
