There doesn't seem to be much information available on the various improved versions of the Swede, can anyone provide me with details on the BJAI, Vais or other designs? Who has reamers? I'm not looking for anything extreme, just a case with less body taper, a sharper shoulder angle and longer neck to reduce case stretch and throat erosion while providing slightly more case capacity. Should I also be considering some form of 6.5x57? Any contact information would be appreciated.
