Hi There,
The problem with Schoenauer's is that in 6.5x54 MS chambering is that ammunition is not so easy to obtain and even cases are not as easily got hold of as once was the case. I recently had a Model 1903 re-barreled but a gunsmith located a new Steyr made barrel already fatory chambered in 6.5x54 MS and that is was what was fitted. The Schoenauer is a wonderful action and although it's the 6.5mm that most folks think of it was offered in 7x57mm, 8x56mm, 9x56mm, 7x64mm, 270 Win, 30-06, 358 Win and I believe also 243 win. The later ones had different bolt handles and there was also an even upmarket model known as the GK.
