I have a 338-06 but on a Savage 110 platform. I'm in the testing phase of load development right now. Groups are ranging from 1" to 1 3/4" at 100 yards for three shots.
WW 30-06 Brass
WLR Primers
Hornady 225gr. Interbond Bullets
48-50gr. of Hogdon Varget
My next trip out I'll be testing loads from 50.5gr to 52gr (max).
I have a post for this rifle in the Custom Rifles forum if you wanna check it out.
