Can't tell you anything about Accurate moulds as I've never had one, but from looking at the shape of the bullet on their website, Ian's pointing to the 311-170F is a good place to start.
When I was looking for the same moulds for my Marlins, I got on the Marlin site and PM'ed Ranch dog and he stated the squarer shorter nose, like the first you listed were made for the Winchesters, and the longer nose like the 311-170F for the Marlins. From that, I ordered the NOE 311-165-RF (RD) in an RG4 Brass, and couldn't be happier, shoots like a dream in all my Marlins sized .311. Mine has the shallow TL design, which I fill full of Ben's Red. I'm running them at 1850 Fps with Reloader 7, also a pointer from Ian.
I am tickled pink with the Dimple Points performance, so ordered another mould in 5 cavity aluminum, NOE SC-311-165-RF, which is for the Winchesters and doesn't shoot well in any of my Marlins! I ordered the second mould thinking I could leave the first RG4 model set up with the dimple point pins and use the second mould for flat points. At the time NOE was taking the listings for the moulds they were out of, off their website and the second mould I ordered was only slightly different in their listing, and evidently I got the last 311-165-RF-(RD), at that time.
To add to the confusion, there have been at least 5 versions of the RD moulds made that I'm aware of, so be careful when ordering one to fit your Marlin.
