If anyone has any load data for the 300WM with the 210 Berger they could share I would appreciate it. I've got a few more of the 210's than the 215's and want to see what size groups I can achieve with the 210. I'm using ADG brass and Federal 215M primers. Have a few pounds of H1000 and a few pounds of Retumbo to try. My gun shoots the 215's very well with 74 grains of H1000. Hopefully, it will shoot the 210's as well or close to as well.
