Cleaned with my Stainless Tumbling Media setup, ran through my Dillon RT1200 trimmer with the CH4D form and trim die, and then ran through my Ballistic Edge model 400 annealing machine. The results speak for themselves, and I'm really happy with them:

Well, if nothing else... they sure look pretty! ;D

Nothing better than playing with cool tools and making your own brass.

Now the question is what powder and bullet you are loading them with and will they be Supersonic or Subsonic, used in an AR or Bolt Rifle.
I ask this as i have a barrel for my AR on order

Alliant 2400 or Ramshot Enforcer. I shoot 240 grain bullets that I make myself, and then coat them in HBN, all subsonic of course. My platform is an AR with the port at .118" in the pistol position. I don't use an adjustable gas block, as all I shoot are subsonics.
