300 Blackout SBR First Sighting and Brass Annealing The Ugly Way

300 Blackout SBR finally makes a range visit. I wanted this visit to be special trying to mimic some HSM 130gr Speer Factory loads with my own hand loads.

There are many benefits to annealing, mainly it prolongs the life of brass but many say it improves accuracy. I went ALL THE WAY IN I annealed for the first time 300Blackout Brass to get as close as I could to the factory rounds.
