Re: back at the bench after 2 years
I picked up a used Dillon trimmer with 2 dies from a hide member. Using a 550b I set up a tool head with a decapper and the trimmer. After sizing and trimming I chamfer and do any other prep the cases might need. The trimmer dosen't really leave a burr but I like to chamfer them any way. I may tumble them for a short time after this. Once cases are ready I have a seperate tool head with a decapper in the first station, this clears the flash holes if needed, second is the powder die, then the seater, the last station is empty.
With the 650 you could put a powder check die in for good measure. A lube die might be a good way to go on the first tool head also(I keep forgetting to order one). I don't think it is a good idea to try to run the trimmer on the same head as the powder die. I don't have room on the 550, you might on the 650 but I still wouldn't do it myself due to the vibration. The motor also gets pretty hot.
Between the trimmer and the attached shop vac, it is LOUD! I throw on a set of ear muffs and go to town.
