Another hobby of mine is to reload. I do so for 7 calibers one of which is the 300 blackout round. It's a pricey round to buy BUT can be made by cutting the top off a 223/5.56 case and then reforming the brass. I currently do this with a little harbor freight saw that takes forever. I don't want to spend $400+ for a press mounted trimmer yet and started thinking bout using my table saw.

What kind of blade would be good to cut brass shell cases? My plan is have about 20 cases stuffed inside a piece of wood which I would push along the fence and cut the top of the cases. Similar to the photo below. It would allow me to trim a lot at once.

I have a bosch 4100 jobsite by the way.
