Looking for starting data for a Seirra 210 MK. 300 win mag. My books only have 200 info. Looking for starting info only. Thanks for the replys.

I use 210 Bergers, and 208 Amax's over H1000
in BHA brass- fed match primers
started at 70gr worked up to 80gr
with no pressure signs
77gr with the Bergers
or 75 with the Hornady's get me under .5 moa
also found a low node at 72 with the bergers
I know its not SMK's but I hope it helps

Save some components and start at 75 and work up to 78 in Winchester brass. In RWS brasss start at 72 and work up. Start with a .020 jam find your sweetspot then back off in .01 increments to find tune the load.
