The Blas(t)er doesn't look so bad in this promotional image. A pretend action scene where the jaeger isn't sitting in a hochsitz.

The .45 Blas(t)er:

The original cartridge made by Romey was designated 11.7x55 -not 11.6x53-, has no headstamp and was made for suppressed prototypes of the Erma SR-100 rifle made by Steyr, and also of the DSR No.1 rifle made by AMP TS GmbH (today’s DSR-precision GmbH). These rifles had interchangeable barrels in 11.7x55 and 7.62x51, and as these cartridges share the same rim diameter and total lenght, both could be used with the same bolt.

Early .45 Blaser cartridges advertised in 2002 as a new caliber for the R 93 rifle have an identical case profile, but it was later modified to have a shorter neck (higher shoulder). I assume that Blaser prefered a case with more capacity and a lighter bullet, instead of using a case with a long neck intended for heavy bullets (e.g., 500 gr). In any case, the original ballistic data was never altered.

This caliber seems to have been dropped by Blaser since 2012.
