This is how I go Bounty-Hunting, for 200k+/h easily. I bring my nicely equipped Viper to a system with a RES that is close to an outpost of a faction you get most bounties of. This to have a quick reload time and just in case that I might accidently hit some cops or clean ships with a stray shot and need to get rid of WANTED status
The trick that does allow the best profits without much disturbances is to NOT jump to the RES, but drop out of supercruise in the ring where the RES is. Just target RES, cruise towards it, reduce speed and slowly go down towards the ring until you TOO CLOSE- EMERGENCY DROP into the ring. Repeat, until you get dropped into an instance with WANTED pirates, might take a few tries. But once you're in an instance with one or more pirates, each time you shoot one down a new one appears ! Target - kwscan - shoot - 3-2-1- next target ... and without cops catching friendly fire or traders/miners disturbing the flow. Pirates come in nice variety ... sideys/eagles/cobras/adders/vipers with the usual bounties 1-15k but also asp/pythons/condas/dropships with 40-100k.
PS: Beware of DANGEROUS Pythons ... these NPC pilots might kick your "rear thruster"
