Looking for the best bullet for vermin to shoot of my AR. Easy button is a 55 grain BT or Vmax. But I want something that will blow to heck when it strikes something as small as a raccoon. Rifle is a Colt M4 LE/military 5.56 1:7”. Wondering how light I can go with that twist that will shoot accurately and won’t come apart. It’s my truck gun when out in the woods and I run into raccoons a lot when checking bear bait so I want something handy to take them out and know that the bullet isn’t going anywhere after hitting the coon.
