The Wolf Magnum is rated for 150 grains maximum charge and designed for use with Pyrodex pellets or similar pellet type powder and 209 shotgun primer ignition.
dr eq = drams equivalent. Black powder used to be measured in drams, which was a measure of the volume of black powder used in a load (basically the amount used). When smokeless powder came along later, both smokeless powder and black powder existed at the same time for a while. A smaller amount of smokeless powder was equal in power to a larger amount of black powder. To keep things simple shells using smokeless powder were referenced to how many drams of black powder would be needed to produce similar results. This continued into modern times. A shell marked 3 1/4 dr eq is roughly equal to a black powder load of 3 1/4 drams. This allows an idea of how much power a shell has regardless of the actual amount of powder that is inside the shell.
You will have to tell us if you are talking about black powder or center fire.
Back when the round was powered by black powder, the "20" meant the amount in grains of the powder charge.

Black powder and smokeless powder are two totally different animals. For all intents smokeless is meant for loading cartridges and black powder is used for muzzle loading fire arms. Black powder can also be used in cartridge loads. You have heard terms referring to a gun in 45-70 on 38-20 or 44-40 calibers. Those numbers refer to the caliber (45) and the amount of black powder in the cartridge (70 grains) Smokeless powder should NEVER be used in place of black powder in muzzle loaders, or in the same volume as black powder in cartridge loads. So depending on what you are shooting both powders have there place.
In my short barrels I use 15 grains of 3F black powder. You can fiddle a bit with the amount +/- to do what you need, but I found it to be a good load for up to a 4" barrel.
Manganese dioxide (MnO2) is a black powder.
Black powder absorbs moisture from the atmosphere
Black powder and smokeless powder differ significantly in power. Smokeless powder is more powerful, providing higher velocities and energy compared to black powder. Smokeless powder's cleaner burn and increased efficiency make it the standard propellant for modern firearms, offering better performance and reduced fouling.
does not matter once the Powder has starch it turns black and the powder can be any color
Yes
Black powder, or a black powder substitute such as Pyrodex. Smokeless powder (modern gun powder) should not be used in a traditional muzzle loading firearm.
