You know I just use Federal bulk ammo from Wal-Mart. $20 + tax for 550 rounds of HP .22lr.
I've shot raccoons with it out to 50yds with good kills. Out beyond that and they will still die but not nearby. At 50 yards I find the bullet penetrates through the chest of a raccoon. I shot one last week at just a hair over 50yds (paced from my position to where I shot it) and the coon ran about 10 yds and died under a bush. When I found it the bullet had traveled through the chest and the coon's lungs and heart were partially drawn out the exit wound that was actually big enough for me to stick the tip of my pinkie finger into it (didn't stick my finger in there, just eye'ed up the size of the hole).
Shot a rabbit in my wife's garden last night - distance from my position to the rabbit was approx. 75 yards. Put one through its chest and the bullet took a diagonal travel path through the body - dragging intestines and stomach out of the exit wound between the rear legs. That rabbit died on the spot.
I also put a feral cat down at 25 yards with a shot from my Ruger Single Six using the same ammo. I must admit I got lucky and hit it in the head - I was aiming for the vitals - but it went down where it was hit. I also took a feral cat down in my neighbor's barn with a shot from my Single Six to the vitals. It jumped, dropped and went into its death throes. I walked up to it while it was thrashing about and put one in its head to ensure a quick death. Distance was about 15 ft.
Every feral cat, coon, rabbit and rat I've killed in the last few years has been with Federal bulk .22lr HP aside from the few I've shot at my buddy's property with his .17HMR.
