The 1 5/8 ounce, progressive burning powder, high velocity Super-Ten load came out about 1925, just as Ithaca Gun Co. was transitioning to the NID.

Back in my college days I watched a Native American fellow shooting 3 1/2 inch Magnum-Ten cartridges in an ancient Damascus barrel Crass Model Ithaca along the flyway out of the Stratford Wildlife Refuge week after week, and last I knew Johnie still had all his fingers.
