My step dad was given an m91 carcano rifle that was in a house fire. The stock is irreparable but the rest of the rifle is in good shape. He is considering converting it to another caliber. he is really considering 35 Remington for the conversion as it seems to be the easiest and a great hunting round for our neck of the woods. Has anybody ever converted one of these to another caliber? Thoughts?, advice,? I should mention he does a little gunsmithing on the side and has a little machine shop on his property.
