The site you refer to is the "Dutchmans" with very good information on SwedishMausers and the Swedish Rolling Blocks. The rolling block that I have described above is still in rimfire and appears to be exceptionaly rare as the Dutchman describes this rifle but states that he has never seen one!!! This example appears to be in its original condition so I have no intention to alter it to centre fire or change it in any way this is definatly a colletors piece which I feel very proud to own.
Many thanks though for you thoughts on reloading, the site you mention should be read and understood by anyone who intends to load for these wonderful rifles as they will bite if incorrectly used.
