Everything from mice to elephants has been killed with a 22. You will need to get a copy of your state's hunting regulations to see what is LEGAL to hunt with a 22 LR.
As said- for squirrel or rabbit sized game, a rifle in .22 LR would be a good all around choice. For bird hunting (dove, quail, pheasant) rifles are not legal. Firearm of choice there would be a shotgun- 20 or 12 g.
Fire all the different types of 22LR you can afford. One or more brands will do better in your rifle.
And your question is??

this rifle should be marked .22S,.22L,and .22LR.
.22 for small game, rifle such as 30-30 or 30.06 for bigger game, shotgun for birds.
