I have my Mauser in 35 Whelen, but for this exercise I would screw the 30/06 barrel onto it. I have a model 69A Winchester I've had for 64 years, and I have a recently purchased Ithaca 37, 12 gauge. I could do OK with this selection. Actually, I have a 30/06 barrel on the Mauser right now; I might leave it on for a while. GD
