I have a #1 in 45/70 with the laminate stock.
Pros and Cons:
Pro: It's the same weight and overall length as my guide gun, yet has a longer bbl.
Pro: Stonger action than any other 45/70, 400 gn JSP at 1900 fps for a starting load (in the Ruger Only section).
Con: Only one shot. I once pursued a bear in the woods, when I was out deer hunting with the #1. I felt a little naked without a quicker follow up shot.
Con: Short throat...I can't load most 350gn and heavier bullets at standard OALs due to the short throat in the #1.
I would think a #1 in 35 whelen would be awesome...18" bbl.
