I just started loading 300 BLK also I made my first batch from some reclaimed 223/556 I got from one of the public ranges. I bought a 6" cutoff saw from Harbor Freight for $49.99 made a jig with a piece of 2x2. My process is similar it goes like this.

Cut 223/556 brass right at the shoulder.
Chamer & Deburr

Deprime, resize.
Trim to proper length.
Chamer & Deburr Again
Prime
Charge
Seat Bullet
