Sportsman's guide has 7.62x54r -> 7.62x25 adapters available. Not that 54r isn't already dirt cheap but Tok ammo is even cheaper and I can shoot it at the indoor pistol range. Maybe now ill get some use from my m44 carbine.

I did see that. The funny one is the .45LC to .22LR converter.

 

Some ranges still wont allow pistol ammo shot from a rifle. Increased velocity, or maybe they just don't want to deal with it.

I've seen similar items and have wondered: Do they eject jusl Ike a spent shell? Does the pistol shell easily remove from the adapter? Are there problems with doing this?

I bought the similar adapter that lets you shoot 32ACP through your Mosin 7.62x54.

It does eject fine and the case falls out easily. Actually it feels somewhat weird no to feel any recoil from 91/30 Mosin rifle

However, while shooting Polish surplus 7.62x25 through my TT33 most of the cases split. Not sure how it would behave while using this adapter.
