Base salary negotiation from Upper Limit

My current base is 225k. private company no equity but there is bonus. In negotiation stage, recruiters usually start from 180k. As a well known tactic, you first hear their range. Since the difference is 45k, I compare with my base and disclose the number. Ideally i want an increment. Is this right approach? what I felt is there is 200k phycological limit for base, nobody likes to go above it much.
