aren't most bullet jackets made of copper? So shouldn't they "fowl" about the same?

No, most bullet jackets are made of gilding metal, a copper alloy that is harder and more brittle, and less "sticky". Solid copper bullets foul barrels more easily because of their stickiness, but the grooves in the newer Barnes bullets helps with that. The old Barnes bullets did not have those grooves and fouled terribly.
