I have a Winchester Model 86 Rifle that is in worn, but good condition. It has full length magazine, and is chambered in 33 WCF. It is marked "Nickel Steel" on the barrell, and is SN 1418xx. I believe it was manufactured around 1910, plus/minus a couple of years. I stopped by WWG last week on my semi-annual trip to Anchorage, and asked about reboring the barrel to 45-70. I realize the loss of collectors value, but 45-70 is a much more practical Alaskan caliber, and easy to procure ammo for. My 33WCF ammo is actually head-stamped 45-70. The WWG gunsmith said it shouldn't be a problem, and he had a guy in mind who rebores other Winchesters for them that knows his business. What do you guys think?
