Making 300blackout brass

[arrowshooter]

No sir. You screw the gauge into the cutter, chuck the cutter in the drill press, put brass in shell holder and go.

I looked at the cost of setting up my Dillon to make 300BLK brass and just bought 2000 rds and called it good.

I make my own 300 BLK rounds cause I like all aspects of reloading and have lots of free time (retired). When I was working I was too busy and just bought the ammo - figured I could use the cases later for reloading. I've made, loaded and shot thousands of rounds, both super and sub-sonic, with no issues.
I have a specific tool head setup on my Dillon to size and deprime the cut cases.
Steps I do:

1. wet clean brass
2. Dry in an air dryer
3. cut cases using HF cutoff saw and Speedy 300 Blackout Case Cutting trimmer. I cut to 1.370" (they stretch a little when sizing). Would love to get the red goodie .
4. debur - I use the Lyman Case Prep XPress tool
5. size and deprime
6. If using 5.56 brass, swage primer hole with Dillon Swage 600
7. cut to length - I use the Little Crow Gunworks trimmer on a drill press
8. Debur, measure length and clean primer hole
9. wet clean brass with SS chips
10. Dry in air dryer
11. reload
