Accurate, powerful and reliable, EXT SHK has a rifle round for all situations where
accuracy and stopping power is crucial, yet excessive penetration is of the utmost
concern.  Tactical urban operations and hunting environments would be ideal
situations for these quality rounds.  All EXT SHK rifle rounds contain the same
NyTrilium core as their legendary pistol rounds, and are guaranteed to provide
maximum stopping power.  At the same time, the chance of creating an exit wound is
greatly reduced, as the NyTrilium bullet fragments into hundreds of wound channels
upon impact.
