I have a Benelli R-1 in 300 Win Mag. I would like to reload for it. It is an autoloader. I have reloaded before using collet dies, I have never did any full length stuff. Anyone have any expertise in this area??? Need some help..Would be happy to pay someone to show me how to get it setup, I'm sure I can get it done after that. I have a set of small base dies, are these the way to go, or do I need a different set of dies. I'm aware of the belted mag case bulge challenges.
