One can find fine but cheap rifles overhere in 6,5x57. One of the reasons this caliber doesn´t sell anymore is because no ammunition is made(or can be found) to shoot fallow deer and stag with. The existing ammunition does not meet the requierements(huntinglaws). The new ammunition found is fine for roedeer.
Fine Steyr, Mauser 66, Sauer 80/90 and early Mauser 98s are just standing in the gunshops shelves collecting dust if the caliber is 6,5x57....

The same thing can be said about 6,5x68Schüler
