The.308 Marlin Express was designed to produce performance similar to the.308 Winchester. This would give lever-action hunters improved performance over their.30-30 Winchester rounds. The table below shows how the rounds compare. Note that reloading data for 160 gr bullets for some of the cartridges is not available.
