SotC is (sans some examples) available online (http://www.faterpg.com/dl/sotc-srd.html). ...Of course, your page numbers help not at all with looking stuff up in the online version, but at least it's got an index!

If you succesfully shoot your target with a gun and deal stress, you can take advantage of their momentary pause to shoot them again before they can dodge; sacrifice your next action to do another attack on the same target at +1 to your guns roll.
At which time the troll/ogre will move up to you, punch you twice through the chest and rip off your head. Unless you're using specialized bullets or really big guns, trolls and ogres tend to be mostly bulletproof; armor 2 and a 10-box stress track means they could take a dozen bullets from the average gun with very well-aimed shots 4 shifts over their own defense roll (i.e. shots to the face) before they go down.
Hmm. That actually makes more sense. I was kind of looking for a way to make a lowly gun toating human more of a threat in the damage department.
Consider stunts for increasing your gun skill, increasing your damage and reducing your enemy's armor (precise shot, maybe?)
You are overstating the threat level a bit. Grenades are weapon 4. This means somebody with supernatural toughness could easily take 10 average shots before going down or 6 really well aimed shots from a grenade launcher. A lot better than the dozen shots to the face needed from a handgun.
OK, so I just finished Proven Guilty again, andMurph is pounding gunfire into a supernatural creature, effectively distracting it so that Thomas can rip it to shreds. Is she Maneuvering or is this a Stunt?(click to show/hide)
Also think of some of her scenes in Changes. How would that look at the game table?(click to show/hide)
