I have also some stock of an old Hercules UNIQUE and use it regulary in my Sako 223 as a quiet round to fill the freezer.-
6.5gr and a home swaged bullet of 55gr to 62gr makes 1600 to 1770 fps and 1" to 1 1/2" at 100 mts.- Good enough for a head shot on a doe red deer.- It print just on top of the lower post of a duplex reticle on a Leupold 3X9 set at 4X.- The idea was to make 22 WRFM+P and it was, and very cheap.-
