I don't have a mount on mine so your comment made me curious. What makes one version better than the other?Don’t get Dillon’s mount, get Inline Fabrications mount for sure!!! One day I may step up, but the Dillon 550 loads plenty for my needs. I would like more spaces on the tool head now I’ve been reloading a lot more. I’ve learned a lot and the less times you touch a piece of brass through the process, the better!! Take your time and have fun!!!
