So far me with my Valmet O/U in 7mm rimmed. It works well with the S&B ammo I found. I still need to get dies to start working up a reload that will group decently. I traded for claw foot rings and for now mounted an inexpensive 4x scope I had laying around. It works fine and I'll maybe replace it at a later time.
Also, does a 45/70 deringer count? It doesn't have a butt stock but it is a rifle caliber.
