You will probably get a bit better first shot accuracy for hunting with a solvent that dries up like Shooter's Choice. If you want to go high tech then Tetra Gun has a bunch of oils, greases and solvents that have some bonding polymer lubricants.
If you are worried about first shot accuracy (long range hunting) the I recommend the following video from the USAMU.
