  It has recently been discovered that some, if not all, classical novae emit
GeV gamma-rays during outburst. Despite using an unreliable method to determine
its distance, previous work showed that nova V1324 Sco was the most gamma-ray
luminous of all gamma-ray-detected novae. We present here a different, more
robust, method to determine the reddening and distance to V1324 Sco using
high-resolution optical spectroscopy. Using two independent methods we derived
a reddening of E(B-V) = 1.16 +/- 0.12 and a distance rD > 6.5 kpc. This
distance is >40% greater than previously estimated, meaning that V1324 Sco has
an even higher gamma-ray luminosity than previously calculated. We also use
periodic modulations in the brightness, interpreted as the orbital period, in
conjunction with pre-outburst photometric limits to show that a main-sequence
companion is strongly favored.
