I want to look at getting a new barrel for my ultra. I have a .223 handi barrel on an ultra frame and I wanted to get a barrel to fill in some gaps in my caliber selection. Right now I have a .22lr 10-22, .223 handi, 30-06 A-bolt, and a 12 guage topper deluxe. I was thinking of a 45-70, but I am not sure about the recoil. Would it be close to the 12 guage with 3 in slugs? I would prefer the 35 whelen, but since they don't make it I was thinking of going bigger. It would primarily be used for Brown Bear in Alaska. Any suggestions would help. I will probably use my VXII 2-7 to scope it with. Thank You for the help.
