Ran across an old, expired thread about this, and thought I add the following:
There are at least two adapters out there for the Mosin. I have both of the ones I know about. One allows use of the 7.62x25 tokarev roundl and the other allows for using 32 ACP/32 S&W Short/ 32 S&W Long/32 H&R Magnum pistol cartridges in rifle. They cost around $15 each. from sportsmanguide.com, all though others also sell them. Haven't been to the range yet, so can't give any report on accuracy, etc., yet. I bought them to have some pot getting options, ballistic practice, etc.
