I have a marlen I am getting bored with as a 30-30. It has a 18 inch barrel. I don't want to go the 35-30-30 because I don't know enough about it. You never see dies for it in most catalogs. I like the idea of 356 but realise that also is a reload only option, but dies are available. What are the pros and cons of this conversion if you have one?
