Long seating 10mm bullets in revolvers...

Compared some of the 10mm Auto rounds I loaded for my GP100 with some 10mm Magnum rounds. Not much difference at all.

Left-10mm Magnum Right-10mm Auto

Makes me wonder about the need for a 10mm Magnum in a short cylinder gun. The 10mm Magnum case is beefier than the 10mm Auto, but that's not very important in a revolver cylinder compared to an auto's weak spot at the ramp.
Much like WB and I have done with our 40 S&W Trail Guns, the same holds true with the 10mm Auto.

The above loaded 10mm Auto rounds works just fine in my Reeder 10mm Trail Gun too.
