Testing this Underwood 10MM ammunition really showed the difference velocity has on energy WOW

Shooting this out of a 3inch and 4inch barrel I initially thought eh ok. But then I shot it out of a 6inch barrel and wow did it come alive.

With the penetration I saw today in the gel, considering most carrying a 10MM for protection I would say is carrying a short barrel semi auto. Do you still think this is a good anti personnel round?

Some experts say with synthetic ballistics gel you should factor in about 15% less penetration in a real world scenario. That would remove about 1.8 to 2inchs from the penetration results.

Just curious of everyone's thoughts.

man what is that load you are running? In a 10mm carbine the pressure is so high on the 1600fps rounds it splits the cases. Pressure builds up higher because of the longer barrel
