What powder does Remington use in 9mm Golden Saber?

I'm fairly sure most commercial loaders do not use canister powders. They usually custom blend their powders to the velocity and pressures they spec out. I friend took apart some Speer 45 Auto ammo from different lots bought a year apart. (3 different boxes) Two of the powders looked similar but different charge weights and the third looked nothing like the other two. All three shot well and have very low SD so go figure. I think that shows the powders are custom blended.

Note: I didn't do the test so I'm going on what he told me but he has been a shooting/reloading buddy for a very long time now.

I remember tearing down a couple hundred or so 8MM mauser rounds from WWII there were at least 5 different propellants I could ID by looks alone. I am sure ArchAngelCD's friends results are more common than we would like to believe.
Truth is, it costs a lot more money to blend lots to match closely. If you have your own ballistics lab why pay that extra.

Yeah, it is not the Secret Sauce Factory Powder, or blended lots, or tested lots, it is that the ammo factory buys powder to specification AND PRICE AND DELIVERY. What you get this month may not be the same as what they will load next month.

Instances I recall:

Glen Zediker wrote that when the AMU got in a pallet of factory match .223, they would pull a bullet and look at the powder. Ball powder went to the shorter ranges and rapid fire stages, extruded powder was saved for 600 yards. The same brand and technical specification, but they knew that ammo loaded with extruded powder was likely to be more accurate. (Which I found in my own rifle.)

An American Handgunner article described the police department that got in a new order of ammo, same brand and technical specification, but it had a brilliant muzzle flash that their old lot did not. Sure enough, pulled bullets showed a clearly different powder and anti-flash additives were not in their contract, so the vendor had used what was on hand or what was cheap.

A gunzine writer got one of the then-new 7mm-08 rifles and some Remington factory ammo for it. He thought the bullet nose looked familiar, so he pulled one and cross sectioned it; Hornady. The exposed powder looked like Win 760. Sure enough, the same load of canister 760 gave a Hornady bullet the same velocity. The first run obviously loaded with commodity components, even though from competitors, to get ammo to the testers.

I pulled bullets from a 9mm and a .45 aluminum Blazer. Both powders looked like Bullseye. Both charge weights were in the normal range for reloads with Bullseye. Was the powder Bullseye?
