Paper patch molds are straight cylinders, no lube grooves. They are also quite a bit smaller to allow for layers of paper. Since the bore of a 30-06 is .300, and the grooves are .308, you need at least .004 thickness,(half), of paper to keep the lands from touching bare lead.

Paper patched bullets can be run at normal jacketed velocities, resulting in good expansion of soft lead bullets. Trajectories are not as flat, lead bullets don't have sharp points as the copper jacketed bullets.

Normal lubed lead boolits that have sharp points have never been accurate. That's why most have 1-R round or round-flat points.
