When I was looking for a solution to a destroyed 25-20 ss chamber in my 44, the gunsmith wouldn’t go any bigger than 32-40, and that with black powder loads only. Ended up with a 357 max chamber, as it’s sooo close to 35 Maynard. It’s been like that for over 20 years. Never finished the project or shot it. It just sits collecting dust. Back then they’re were a lot of warnings to stay away from anything like 38-55, 45-70, etc.
