Howcome .25 left out? ( The 25/308 or 25 Souper )

[Alan in GA]

so you have a cylindrical case body? I read an article on zero taper cases somewhere [Rifle magazine?] and it seemed there were 'not' the problems a zero tape case would seem to have. Extraction was fine with his cartridge, too.
Responses like yours makes me think once again about building the 'perfect' 25 caliber round using the great, tough .308 case. My .250 Savage Ackley Improved is as close as I've gotten to the 25-08.
