Put out anything that will make them stay long enough to give you a good brain shot. I like using plain dry cat food (seafood flavored) because it makes them hang around for a few minutes to eat, but all the other suggestions work great too. BTW, they do not all eat the marshmellows. I put them out on one side of the cat food bowl and only observed a young raccoon eat them. The adults were eating the cat food and did not seem interested in the marshmellows. I guess they preferred the protein over the sweet stuff at the time. Some advise - if presented with a frontal shot (my favorite), wait until the coon puts its head down first, then shoot just at least 1/2" above the eyes. Whatever the position of the coon's head, the trajectory of the pellet should always be towards the brain, or the back center of the skull. This means having to shoot at various spots on the skull to achieve the right angle towards back and center (of ears). Shots to the back of the head are not recommended. Make sure you compensate for the distance if too close, with the appropriate holdover. Good luck!
Just make sure you hit their brain and you shouldn't have any problems. "Between the eyes" or between eye and ear will do it, as long as you don't shoot too low and hit a jaw bone, etc. The pellet must go in the brain so you need to aim at the upper half of the skull with a broadside shot. Which airgun will you be using and what pellet? I am not sure you want to shoot them in the garage. They will spray red stuff everywhere! Not a good idea to shoot them indoors You will be cleaning up for a long time.This is what the ground usually looks like (or at least when shot with a powerful .22 airgun) which you cannot see on a green lawn that well, but can see it clearly in the snow and on a garage floor. It will get all over the walls as they do their long death dance (usually 15-25 secs.) and bounce off everything in the garage Shoot it outside if you can because they might also break stuff in the garage and make a mess during the death dance. You will have 15-20lbs bouncing around and hitting things hard.. plus you will have this:
Bandit's have super night vision and hearing so a good concealed sniping spot is a must. I've taking load's of Bandit's on my night patrol hunt's and all the Bandit need's to see is the glint of light of your scope glass to send them running. Ed
