>>1976204I've shot squirrel with 5.56 so basically same. No damage to meat at all, they are small enough that the bullet passes through without creating a cavity. You're fine.
Lots of ways to cook squirrel, just google recipes. The meat may be a bit tough so a lot of times you should boil before proceeding. Here's a deep fried one shot with 5.56. Serve your guest of honor the tail ;)
