How do you make 20 tactical brass - Page 2

Several ways to form 20 tac brass have been posted. Use the one you find
is best for you. My method is simple and less dies to purchase. To each
their own.

I have formed over 1000 222 brass from military 223. If you polish the inside of your die very well, it alleviates this problem somewhat. The most common cause of wrinkling is too much lube during the forming process. Imperial sizing wax is in a class of it's own for reforming brass as well. Just a light application, with none on the neck at all works well. Cycle the ram slowly helps. If it is still happening, stop half way, retract and turn the brass in the shell holder about 90 deg, then finish the stroke. With 20 Practical, I take the 223 neck down to 204 in three stages, 223 sizing die with no button, then using a .233 intermediate bushing and my final bushing.

Any decent brand of die will do the job. Some just prefer, say Redding, etc.
Your choice and money to spend on the one's you want.

Okay thank you. I was just a little concerned cause it seeems the brass dimensionally is the same, and it chambers perfectly, it’s just the necks are shorter and was concerned more about that. Worried about the soot blow back (dirty brass and chambers)

You should have no issues, in time the necks will more than likely grow and you will take it from there.
Don't get wrapped up in details, it is a simple cartridge to develope and play with, like the 20 practical. K.I.S.S.

Brass is ready to load and shoot. I have 2 20 tac's and have formed 100's of brass.
My shooting buddy also forms his 20 tac brass this way.
