I'm sorry to inform you, but the .25 Stevens was discontinued in 1946. even if you could find some ammunition, it would probably be extremely expensive. Although I have heard of people re-chambering these rifles to the .25ACP round.
Ammo in .25 rimfire has not been available for many decades.so the answer is no.
In North America, it's sold as .25 ACP. In Europe, it's sold as 6.35mm.
Stevens 25 Rimfire ammunition has been obsolete for many years and is now an expensive collectors item and when available it is in very limited quantities. Shootable quantities have not been available since before 1960.
I can find no listing for a J. Stevens model 80. There was, though, a model #83 bolt action made in various rimefire calibers including the .25 rimfire. This firearm was discontinued in about 1942. I find it difficult to believe that many .25 caliber models were made that late though. Unless you were to find an avid Stevens collector I doubt if you could get more than $300 for it as ammo is just about imposible to find.

A Stevens Arms Model 287 is a Semi-Automatic .22 Cal Rifle. Ammo is fed thru a tube that under the barrel.
2 types of 25 caliber Stevens. 1. In centerfire, you have 25-20 Stevens and I believe 25-50 Stevens of which brass is available from Midway. 2. In rimfire you have the 25. rimfire round which apparently is unavailable as I am currently searching for a source.
22 mag rimfire. say it on the gun.
