    I inherited an F-class/LR Benchrest rifle chambered in 7mm Shane. I'm not having much luck finding any information about this chambering. The inscription on the barrel is 7mm SH but there were some notes describing it as 7mm Shane. I can always rechamber it to something a little easier to deal with, but I'm mostly curious. The rifle is a Barnard action in a McMillan Stock and a premium barrel, probably a Bartlein with very low rounds through it. It's got a Nightforce scope on it as well.

    I think you are referring to a 7mm Shehane. It is a "straight" .284 with the sides moved out for an increase of 3.3 grs of water. That REALLY translates to right at 1.0-1.5 additional POWDER capacity.

    Thanks for the reply. I think I once asked my friend about it and he said it wasn't Shehane, but Shane. There was also a For Sale sign saying it was 7mm Shane. Sounds awful close, though. I'm still going through a bunch of stuff and haven't found dies or cartridges for it yet. This was part of a gunsmith's personal collection and a lot of it is non-standard.

    PTG Reamers had a clearance on , if I remember correctly a Shane reamer . You might try contacting Dave if he knows anything about it .
    Back to my previously scheduled nap !

    Order a block of cerrosafe and cast the chamber and see what it is if you really doubt that it is a Shehane.
