Here is the reply I received on ballistics;

Still developing, but here is some data:
120 grains Blackhorn 209 with 250 gr TMZ ~2069 fps
120 grains Pyrodex Select with 250 gr TMZ ~2031 fps
120 grains Triple 7 FFG with 250 gr TMZ ~2050 fps
Hopefully by next fall it will be in major sporting goods retail stores!
