Lead is very slippery, thus has a lower friction coeficient and is less abrasive than copper.
The only thing I would concern myself in this case is:
Start with a light load of fast burning pistol powder and increase it till you get the velocity and accuracy you want or until you start to see leading, minor light dust is not a problem and I would not go any higher, sludgey means your pushing too hard.
I would not load a non gas checked lead bullet above 1300 fps.
A max load with a hardcast will generate dangerous pressures with a softer alloy.
If you want to hunt, some LBT's with gaschecks will go as fast as your wrist can handle.
An "ALL COPPER" , not copper clad steel, "ALL COPPER" "chore boy brillo pad" from the supermarket, unrolled and wraped around a .30 cal bore brush until it is thick enough to be a snug fit in the bore will clean the nastiest of leaded barrels in about 15 strokes.
