Need load data for 300 Jarrett and Berger 210gr VLD. I have H-1000 and Retumbo on hand. Can I just use 300 Weatherby data and work my way up ? However, can't find loads for 210gr Berger.
I sent off an e-mail to Berger Bullets for load data, but thought maybe someone on here had some info.

With the vast # of shooters on this site, is there not anyone out there shooting 300 Jarrett or 300 Weatherby with 210gr Berger VLD and Retumbo or H-1000 powder with load info. I will just start low and work my way up I guess.
