How many grains of Blue Dot are you using to get to the 2500 fps mark. I'm looking for something fur friendly that will still dump them in their tracks. I was considering the 17 fireball but this may be better yet, how is it as far as noise. That was my concern with the fireball, I don't want something too loud. I previously used 22 mags and 17 hmr for calling coon, both worked fine but neither was a drt killer, and that is kinda what I'm looking for.
