I bought a 300 RUM last year, and have been shooting factory fodder to build up a supply of cases to start reloading with (rem brass). I'm finally getting enough brass together to start to seriously thinking about purchasing reloading dies. I've been thinking about going the minimalist route - skip the full length sizing, and neck size only. Up to this point, I've always full length sized everything, but since the RUM is such a long case, I would think full length sizing would probably result in some pretty serious case streching. Is this a good idea with the RUM? What brand of dies should I be considering for doing this/ what dies have you had good luck with? How do you decap the primer when neck sizing only?
