The hardest chambering to find in left hand classics are the 270's blued or stainless... their were two distinct runs of the lefties the first batch were all low 6 digits in the area of 117xxx the next run were in the 7 digits if I remember right majority of them were chambered in the wsm''s
I was hoping you would chime in. I know you also bought a left hand WSM and it's been a great rifle, if my memory serves me right..
