I've been den calling now for about 15 years and average about 50 a year. Started out using 17HMR, and switched to the 22 mag, after having several coons hitting the ground and taking off. The 22 mag does a good job, but have to sew up exit holes sometimes. Picked up a Savage A17 WSM and been using it this season with 25gr load and will be using it from now on. Went out and hit a couple of trees, getting 9 coons and only had one hole to sew. 17 Hornet with the 25gr load is another round that works well.
