The “BAT” overlabel is found also in red color print on white. In fact, I had not seen the black one. I have the red one over both the police boxes and the commercial boxes. While some of the literature I have on this cartridge from Dynamit Nobel A.-G., refers in text to the "Action Safety Bullet, titles and box labels all refer to it simply as “Action-Geschoß” (Action Bullet), on both the commercial and police boxes. The cartridge came out about 1981, and has a 5.6 gram bullet. Like many of these “wonder bullet” rounds there is more than one type of the Action bullet.
The box shown appears to be one of the police boxes, with overlabel. If it is, it will say:
9 MM PARABELLUM
5.6 g ACTION-GESCHOSS
LOS DAG (DATE) (MY OVERLABELED BOX IS 2/31 AND MY BOX WITH NO OVERLABEL IS 3/81.
The Action Bullet cartridge was made in .357 Magnum also, which initially, seemed to be unknown to German collectors. A good friend of mine and well-known German cartridge collector saw them and heard of them first while visiting us and the store I worked at, and saw them on the shelf. He had never heard of it. This round was not in many commercial catalogs, whether domestic or export. I have not looked through all my catalogs to see when they started showing it, and when they stopped it. RUAG has resurrected a form of this round commercially, and currently.
“BAT” supposedly stands for “Basic Action Trauma” round, but I can find nothing in my Geco source material so describing it. I certainly don’t have all the literature that the factory ever produced on these cartridges, so can make no further judgment on the origin of that term. However, it sounds suspiciously like American advertising hype.
By the way, if you could see the whole labe in the picture, you would find that the bottom line of print starting as "“Manufactured by Geco Div…” gives the "Action/Safety designation, along with the bullet weight, but it is wrapped around the box and on the box pictured would appear on the end of the box. The red labels are identical in content to the black one shown.
