I don't see how you won't need a reamer. If you rebore your 300 barrel to 358 you will not have a neck in the chamber. Someone would have to be able to get your barrel perfect in the lathe and cut a neck with a boring bar. Not the easiest task to pull off correctly. Then you need to run a throater in it. Just get the reamer then when you want a new barrel you have it. If your smith has a whelen reamer you can use it to punch in the neck and throat. Just some thoughts on what you said. 35 saum sounds nice. Personally I like the 338 fed. Over achiever of a round but won't fit your bolt face.
