My ‘47 reamer print (note .180FB).
Below is a visual of 130 Ber VLD(H) seated .010 off the lands. Note: Position of boat tail taper colored red.
I have at least a half dozen barrels chambered with this reamer, been shooting it since 2010.
The CM could have been named a 6.5 X 48.8
. The big brother is the 6.5 X 51 AKA 260 Rem.
