[quote=tex_n_cal]Might be an interesting caliber for a Ruger #1...that's a hint, Ruger
The extractor on a SS works best with a rimmed case. Rimless cases can be made to work with a spring loaded extractor. It seems a rebated rim makes the extractor engineering even harder.
I don't know how many rebated rim rounds are chambered in the #1. Probably not many.
The 26 Nosler has a std. mag. .534" rim and a .550" case body.
Most current Ruger #1 Chambering's are rimless, I personally have not had extraction issues with any of mine, 204,.22-250,243,270
