I'm not entirely sure what you're complaining about. Those of us without access to imk2's think 80% returns is as good as it gets and 50% is routine.
Tips: Kreltins might be too hard for your weapon, your returns were much higher with feffs and weaker mobs. Imho, ideally you want a main weapon that does X max damage, 2X for crits and use it against a mob that has a max of 3-4X hit points (so you kill the mob in maybe 5 shots max.) Then, keep another wep that does 1/3X to 1/4X to finish it off. I used a melee weapon to get str. Baby troxes, feffs, medium allo, estophyl, etc. are good for their fast regen/lower no-loot rate. For the amount you cycled, imagine one less or one more shot per kill over thousands of kills to calculate the difference.
For extreme eco hunting, Star put up some videos. S/he used an imp fapper and went without armor to hunt dasps and such. No deaths, no healing pauses, just shooting.
