Personally I use Rogue Hunter (endgame melee weapon, huge stats), bounty hunter set, and stat upgrades from Dr. Choppy (you get the blueprints from shine town, 1000g for upgrading one stat by one point). The main focus would be grinding bounties, iirc the “woman at tribal village” gives the most gunpowder/points. Both Rogue Hunter and the armor can be obtained at the shine town bounty office, great endgame loot.
