Mark 7 Powder Check Centering Die Bundle — Buy 3, Get 1 Free — common questions
Is the Mark 7 Powder Check sensor included?
No — these dies upgrade the Mark 7 Powder Check probe you already own. They center the case to the probe and increase airflow around it, ending powder spills and probe strikes on the case wall.
How do I pick my 3rd and 4th calibers?
The bundle ships with 9mm and .223/5.56. Add the calibers you want for dies 3 and 4 in the order notes at checkout — any of 380, 40 S&W, 10mm, 45 ACP, 300 BO, 6.5 CM, or 308, or ask about a custom caliber.
