Ok lots of helpful info, now back to 40grain naildarts which are 2.6g. They will be plenty useful when hunting crows and pigeons, so fpe will not be a problem. My only concern is, with a relatively light dart (40+grains) fired @ +280-300Fps. Will it fly accurately enough to bust crows and pigeons out to 10 yards-15yards. Id learn that the cones must be very steamline and have a good seal on the barrel for a start.
