Hey Jon,
Chi is correct. The most accurate way of finding the true mass bias is by using a determinator. I'm not sure who in the area even has one, maybe Rod Ross at Manteca? Or you can contact Lanemasters in Stockton to see if they use one in their factory and see if they'd do it for a fee. Sorry bud, this is about all I can help you with on this.
