The 500's have some improvements over the 300's but I don't remember exactly what thet were. If you are going to cut soybeans in rows narrower than 30 in the the 500 is the way to go. I had 2 300 series heads and in narrow row beans they knocked out a lot with the wide snouts. company rep told me once that the 300's were designed for 30 in rows.
