Tinker I posted pics of the 12 Bore in the bore rifle section.

thanks for the info. Between the two posts, I think I will be looking for a Merkel in 470. Saw a Kreighoff single trigger at a good price but I am unsure about the cocking mechanism? any word or advice on that? Sounds like the .458 in a double has potential problems being non-rimmed so I will just avoid those problems. thanks again
