Solid copper is lighter than lead so more is required for a certain weight, bullet is longer, usually increasing the bearing surface, resulting in more friction.

So requires less powder and/or slower powder to keep pressures to an acceptable level.

The exception to this is a bore rider projectile like a Cutting Edge,

The bearing surface remains the same so they have completely different characteristics to "normal" projectiles.
