I cant find this answer anywhere but I know with the 26" barrel there's not too much benefits of using more than 100 grain.
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.
Variations in projectile weight, velocity, powder charge
If it is a Thompson Center Cougar it is meant to fire a patched round ball or mini ball style round, (conical lead bullet aka maxi hunter, buffalo bullet etc.) With the relatively slow twist of the rifling 1:48 it will fire Sabot bullets but will not be as accurate at ranges past 125 yards, Maximum powder charge should not exceed 100 grains. All in all it is the same mechanically as the Hawken .54 and I believe you can still download the manual at the Thompson Center website.
75-100 grains of powder.
Amount of powder used.
600 NE- 900 gr bullet, 145 gr Winchester 760 powder (slightly compressed) 700 NE- MAX 250 gr VVN powder + 2 gr Bullseye as a base charge.
One tablespoon maximum
The CHAMBER of a firearm is the part which accepts the loaded cartridge or projectile and powder charge. It is usually found attached to the breech end of the barrel. It contains the explosion/ignition of the powder charge and allows the projectile to exit and travel into the barrel under the pressure from the expanding gasses from the ignited powder charge.
Powder paint uses electrostatics by charging the powder particles with an opposite charge to the object being painted. This creates an electrostatic attraction that causes the powder to adhere to the object. When the object is heated, the powder particles melt and form a smooth and durable finish.

50-350 depending on specifics
Back when the round was powered by black powder, the "20" meant the amount in grains of the powder charge.
