I am with BASDJS on this. I am relatively new to the .17 family, I am currently using a Specialized Dynamics, 18in flat top AR-15 in .17 rem. While it's not a fireball, the performance is similar.
I was originally worried about damaging the fur on foxes and bobcats. The second weekend I had the rifle I dropped two foxes, one at 40 yards, one at 25 yards, and absolutely no fur damage at all. There were two holes, and the damage under the fur was incredible, and they dropped in their tracks.
Next I was worried about the stopping power on the larger predators. I had read from a lot of guys about the 17's and stopping, but I needed to see it with me behind the gun. The 3rd weekend I had the gun, I folded up a bobcat at 80 yards, one shot. No exit hole. And again the damage was amazing.
The final test was a coyote, which we called in to 92 yards, and again one shot, one kill, one entry. And again total devastation under the fur, but no fur damage.
So I cannot say enough good things about the caliber, and the fit with an AR is just what the doctor ordered. You will be happy.
