I have a Marlin 30 AS that was rechambered to 307W by R. Nonneman. Shoots great and functions perfectly. Nice thing about the Marlin is that it also functions with 308W brass. Also have a Marlin 30 AS that was chopped and rebored to 356W by JES. Another conversion that shoots and functions great. They are two calibers that were very unfairly treated by the shooting public.
