The News Outside

So…my question is:  Does anyone use it?  I’m considering building an AR - not to fill any niche - just as a fun little tinkering project.  However, I’d like to do something different than the standard .223/5.56 or .300BLK.  The intended purpose would mostly be punching holes in paper with the occasional coyote hunt.  I’d love to hear some real-world results before I dive in headfirst!
