Don't shoot the 300 Win Mag anymore, but when I did, the 200 Partition and Norma MRP were the ticket.
In my #1 308 Norma Mag, I chase the 210 LRAB with a big charge of Retumbo. Flirts with 2950 and is a
sub-moa load. Shot a Bull Moose at around 120 yards in 2019. Bullet exited and moose was down quickly.
I have used IMR 7828, H4831, Reloder 19 & 22 with 200 grain bullets. All worked fine. FWIW, I am not a
big fan of the ELD-X either. You never know when you will get that close-up shot that really tests the
integrity of a bullet. Dave.
