RE: the Extreme Shock "fang face" Explosive Entry ammo: Stats on this round indicate it is devastating on flesh targets (mfr says one round killed a 505 lb Russian boar within seconds). It creates a sphere of tissue destruction about the size of a grapefruit. But--since it would not feed reliably in the R9S, I elected to use one of these rounds as the first one out the tube in a 6+1 loading; that way I still get one shot of it off but don't have to worry about feed reliability.
