Nice data. I like my P2kSK in .357sig, and might have to check out those Underwood rounds.

Almost 1600fps with an all copper bullet is going to wicked! That's really where this round shines, or so I've been told in regards to pushing bullets past 1400fps mark.

The recoil doesn't feel any more than the others. Less if anything. Noise might be a little higher pitched, but muzzle blast is the same. Also, no over-pressure signs at all. They shoot a little lower.
