Soft Swaged, precision manufactured, a South African original.
Weighs in at 13 grains, the hollow tip is soft and will readily expand upon impact.
There are no machining marks/cast lines on the slug exterior - they have a soap smooth texture, however, shed a lot of graphite on one's fingers when handled.
The rear is deeply coned in, whereas the frontal hole is also conically ingressed.
Therefore, bullet-shaped and will traverse longer distances at higher muzzle velocities w/out fear of spiraling or tumbling as is the case w/ diabolo pellets.
Hard-hitting - strikes w/ a thunderous clap whatever it hits against and will switch your quarry off neat and cleanly milliseconds after impact.
