I would be interested in trying this stuff on some gophers. It looks similar to the Quik Shok, but I'm guessing it could be used in match chamber barrels.
Segmented Hollow-Point
CCI's unique Segmented Hollow-Point (SHP) bullet is now available in 22 Win Mag and a 22 Long Rifle subsonic load. This offering is ideal for bigger targets that require a larger wound area and makes perfect sense in the 22 WMR. The flat-shooting SHP is designed to break up into three sections on impact for even more stopping power. These three segments diverge from the main path for unique terminal performance on game. The subsonic 22 LR offering is great when hunting around a populated area and a quiet, effective round is needed.
FEATURES & BENEFITS
• Unique bullet design segments on impact
• Great for larger targets
• Combines flat shooting with extreme terminal effects
• Available in subsonic 22 Long Rifle offering or 22 WMR
