Has anyone used TW 30-06 brass ? How is the quality ? How does it compare to factory brass ?
I'm asking because I want to make a bunch into ackley improved for a new rifle. I have 500 so I would like to use them. Thanks

TW is US Military brass from Twin Cities Arsenal. It is good stuff. It is thicker and you should reduce your loads by 1 grain from the book.

TW, Twin City, Arsenal was operated by Federal, at the time they took it over they had never made a metallic case, they had only made shotgun hulls, There are not many head stamp dates I do not have, I have formed 8mm, 7mm, 308 W and at least 5 other cases using TW cases.
