To address the OP's actual question: unless you use a RAW processor that duplicates your camera's JPEG conversion engine and whatever customized settings for it you've created, you're not gonna get a .jpg file that looks exactly like your OOC JPEGs. If you don't have such a processor and that JPEG look is important to you, continue on as you've been doing.
