I never ran 180s in the WSM Montana, but in this Classic they are a definite step up in recoil.
Not terrible by any means, but getting past what I call noticeable.
I am tempted to grab another Montana, as I really prefer the 8400 stock to others, but I can’t put this SAUM down. Had Shaen put on a modified Lilja 8400, and for me, it’s about as good as it gets.
