Do a search. I have a Tikka 512 whgich is basically the same as the Valmet 412.

With double rifle barrels in 9.3x74R which I have used a bit in Australia and Africa. And double rifle barrels in .30-06 which I have not used.

Combination barrels in 12 gauge and .223 which I use a fair amount on my farm. Also a set of combination barrels in 12 gauge and 7x65R. I have not used it yet either, but will soon finally be getting some ammo for it.

12 gauge U/O barrels. I have used steel shot with it. But prefer lead shot.

My Tikka 512 used to have a single trigger. I had double triggers put it on it.
