"Little screaming pill" I like that! I call my arrows the whisper stick.I've killed a black coyote here in Northwest Georgia, and 3 more besides mine have been taken on the same land in the last 3 years.
A Thermal Imaging Scope doesn't care one little bit about what color they are in the cow pasture at night. The black ones get the same 62gr. Lehigh Defense Controlled Chaos Bullet that the gray ones do... usually, they're absolutely D.R.T., just like a bank safe was dropped on their head when that little screamin' pill hits them...
