Thread: Forming 221 Fireball / 20 Vartarg brass

Thanks again, guys! I tried the hacksaw but it kinda galled, lots of elbow grease and ended up with a bad finish around the case mouth. Previously, I was thinking about those Renovator tool, but was afraid to spend some money on that and it didnt work. On Youtube you can see some people making 300AAC out of 223 and most of them use this mini rotary saw.
About the annealing process, nothing special. Just a Bernzomatic propane torch, a cordless drill and any clock that makes some noise/tic tacs so I can control time. But in the near future I will build a proper annealer myself.
Here are some self explanatory images continuing the process.
Cheers

Simple ingredients to mak'em shine

kg copper cleaner works great for cleaning brass off the expander mandrel. I have the k&m neck turner but found it fiddly i then got a pma tools turner its much nicer to use with a micrometer style depth adjustment and the cutters come with different angles to match shoulder angles for running into the shoulder. The pma cutters are broader so its much easier to get a clean smooth cut than with the k&M. The expander mandrels are nicer too with an eliptoid shape to them http://bulletin.accurateshooter.com/...-turning-tool/
you can buy a sleeve from pma that allows you to fit the carbide mandrel from the k&m to the pma turner so you can still cut the donuts. That carbide mandrel runs so much smoother on the brass than standard steel mandrels its the one really nice thing about the k&m set up
