What is a good 22lr ammo and grain for varmint hunting and small game?

If you don't want to keep the meat CCI Stingers are what I would reach for. If you are after squirrels or rabbit and want to eat it, a standard velocity 40 gr bullet will do the job just fine.

Well on squirels I'll keep meat nd rabbits but like pests that come in my yard I wanna know when I hit em it's gunna tear em up so I'll go buy some stingers after work and see what them can do

I would just shoot what was the most accurate. You should find as allready coverd one of the 40gr sloids that advertize velocity below 11fps will be more accurate. Something l;ike wolf/sk ot federal 711B, or CCI standard and maybe agulia match. Depending on your rifle most can shoot minute of squirrel head at 50 yards.
