I'm trying so hard to make a "caliber wars" comment regarding that post.No rcmodel,I'm sorry for snapping back.that was uncivilized.
Lead council,it is a 300wsm case,I tried an '06 case first but it was too long and skinny.when I ground the knob I made sure and stayed as close to the centerline of the shaft handle so the case wouldn't be any closer to the scope than the factory knob.
