look at hornadys lock and load .....
The Dillon is a better and more flexible machine...

The 550B include (off Dillon web site )
The basic 550 includes:
Machine with caliber conversion kit (shellplate, locator buttons, powder funnel) in the caliber of your choice.
Powder measure with standard large and small powder bars (small installed), Small bar throws from 2.1 to 15 grains of powder Large bar throws up to 55 to 60 grains of powder.
One prime system with large and small priming parts.
One large and one small pick up tube
One toolhead
One powder die
One loaded cartridge catch bin
One written instruction manual
One set of standard Allen wrenches
No dies are included. If you do not have any dies, you should go for the Dillon dies.
The manual indexing is great if you plan to reload many caliber. If you make a mistake or are not sure, you can go back on station without problem.
The big + of the 550B is the easy caliber change - be rifle or pistol.
I have a least 400000 rounds loaded on my 550B, pistol & rifle and I will not change it for a Hornady even if it was given to me..
