210 SMKs

[sewwhat89]

Has anyone worked up some accuracy data for the 210 SMKs launched from 300 WM?

I was thinking of starting with 69 gr H4831sc and/or 75 gr H1000. Any suggestions?

It looks like 76.5 gr H1000 may be the ticket. I worked up to 78.8 gr with no signs of excessive pressure. 79.2 H1000 or so may be the next good load in my rifle, but I think I will stick with the 76.x gr load.

69.5grs. of RL22 w/Rem 9 1/2M primer works nicely for me. .005 off the lands. Semper Fi
