I believe that Pedersoli still offers their 86/71 in 348 but good luck finding one. Probably easier and smarter to spend the money on a real Winchester and just be done with it, or find a Browning 71. I was very lucky and was gifted a friend's Model 71 a few years ago. We traded rifles for a while, I let him play with my Pre-War M70 219 Donaldson Wasp and he let me play with his Model 71. When he moved away from gopher country he sent the Wasp back to me and once he was settled and I asked for his address to ship back the 71 he told me that it made more sense for me to just keep it.
Long story short, I need to shoot something with it.
