Here’s a quick tip for range training from Steve Aryan of Grey Fox Industries on squib safety. If you are not sure if there is a squib projectile lodged in the barrel of your handgun or rifle, lock the action to the rear so the bolt is open and daylight is shining into the receiver area. Then get out your smartphone and take a photo up the barrel. You will easily and safely be able to see if the barrel is clear or not.
