Susan, this is chambered for .22lr, so anything that says .22lr. (lr is long rifle) Being a revolver, this will also shoot 22 shorts and 22 longs. The 22 short, 22 long, and 22 long rifle all have the same rim, base, and neck diameter on the case. The difference between the bullets is mainly in the weight (grain) with the 22 long rifle being heavier and longer compared to the 22 short and 22 long. This means that you can fire a 22 short or long in a 22lr revolver. Any of these .22lr's will work, no matter which grain you choose. If you are using it for self defense, choose hollow points. budsgunshop.com/search.php/type/ammunition/caliber/10000844-22+long+rifle

Susan, this revolver takes 22 long rifle ammo. I have a similar model and it will safely fire any 22lr/long rifle ammo you can find. If you click on menu, then products, ammo, by caliber, and lastly 22 long rifle it will show all of the 22 long rifle ammo buds has in stock. Any of those will work just fine. Hope this helps.
