Its not something I am going to use often as it would take a toll on the barrel. This just looks fun to do every now and then......shooting is about learning new skills.....and having fun. Everyone I know who has shot one has nothing but extremely positive things to say about it.
This contraption brings to mind the old Chesty Puller quote that adorns a tree at the Sniper School near Camp LeJeune, NC...
“One shot, one kill.”
