Actually, it seems that the BoA gun at 49 (81-121, 2.9 Speed) + the 18 DPS Ammo (Rockshard Pellets) from BRD's Lord Roccor will be better than the best 49's gun (Guttbuster) using that same ammo + scope or the Verdant Keeper's Aim + scope + Jagged Arrow (only 13 DPS) resulting in a top end damage of 173 for UDHC, 170 for VKA and 171 for Guttbuster. UDHC also has the highest low end damage of the the 3 and slowest speed. Autoshot + Multi/Aimed shot + Arcane Shot + Auto Shot bursts from UDHC will be reliably higher than with the Guttbuster or Verdant Keepers Aim, though VKA has the highest burst "Potential" because of that proc. Additionally, the VKA can be given the +30 Ranged Attack Power scope. I remember reading somewhere that the hit cap for the bracket is 40, so between this and Sure Footed, you can hit cap easily, making this a highly valuable to Hunters playing more of a control roll.
Basically... have fun choosing at 49.
