Here are three pictures of my 16-4, with it's 8 3/8 inch barrel. Should I modernize it and have the cylinder reamed out for the .327 Federal cartridge, or should I leave it alone in it's current .32 magnum configuration? Is there a significant ballistic improvement to the .327 to warrant the expense? Is there any collector value to the original configuration? What would be the pros and cons of either? Thank you in advance for your input in my decision.
