It looks normal to me John. I believe you Dies are made to an industry standard that manufacturers adopted in the 1930s. Your Krag was chambered to dimensions decided by the U.S. Ordnance Department in the 1890s.

I suggest you 'back-off' your F.L. Sizing Die one turn and enjoy the virtues of 'fire-formed' brass.

p.s. - Humor me and see if one of the cases fired in your rifle will fit in your carbine, without resizing.
