I was reinspecting these casings again today under magnification, The *Star-Line* case as shot from my S&W 1006 the one that had the loose primer before shooting and leaked...upon closer inspection it shows a very faint "SMILE" line. It is posible I missed it originally (remember this was used brass and the primer pocket was loose). That casing was pretty well beat up just look at the head stamp!
The area of the "SMILE" is to the left side of the casing and isn't even visible in the picture. It is possible I ironed it flat when I sized it in the "Pass-Thru-Die".
But I really think it was produced when I fired it with the 9.4 grain charge of LongShot that copied SwampFox's 1240 fps loading...remember I have never seen a "SMILED" casing from my pistols. This may have been the start of the very first one.
I believe *Star-Line* cases are very soft brass as compared to others brands.
