Well, I took some measurements and fed em to the tech at hornady. He seems to think its within spec.s
For a 460S&W, webbing should be 0.478" and all were and are after sizing. In front of the webbing is .471". He said its a tad tight but normal. I guess its just because these 460 cases are so long.
I compared with Starline brass, and got close. The hornady brass is thick at 13.5 to 14 mil, compared to 12.5-13mil on the starline.
