The only issue with either is that it is what it is and always will be. Dillon has another option The 550 B basic loader. Instead of moving the dies you have a shell plate that moves. This makes it a limited progressive or can be operated one case at a time. Instead of batch loading you just move the shell plate through the stations and end up with one completed round. I use my 550B with the powder measure removed for rifle rounds and have relegated my old single stage to bullet pulling. If you want to make ammo for Handgun competition or recreation then you will want to end up with a progressive this press will allow you to add the components to make it a full fledged progressive. If you are making ammo for bench rest you sure don't need any advice from me.
