I've got three cans of Elephant 2F left from about 7 years ago. It's exceptionally dirty stuff but it does get a load out the end of the barrel and on it's way. I wouldn't hunt squirrel with a .45 cal rifle. Last time I shot one, it came outta the tree in two pieces. That said, I don't hunt anything any more but if I did, I'd use a smaller bore rifle.
