Commonly recognized as range fodder, some old-school cops preferred to carry semi-wadcutters as their duty loads instead of hollowpoints (some municipalities actually insisted on "solids" because they considered police use of hollowpoints distasteful). I certainly would not feel naked carrying these in a (non-ursine area) woodland walkabout K-frame revolver ... or for most any other self-defense scenario.
Federal no longer offers this load and IMHO they never will return it to the product line. The law enforcement market has moved to semi-auto cartridges. The civilian market for a load such as this is pretty lean.
For those unfamiliar with the "Nyclad" moniker, it is a gun industry portmanteau of Nylon Clad; the blue color of the bullet is a Nylon coating over the lead ... the intent is to minimize airborne lead, barrel leading, etc.

Sealed primers ... plated cases ... this is some really great stuff!
