Here is a thread and a quote from earlier today...........
Chris Costa on HD shotguns and handguns
Also, itís worth noting that during my courses or when I shoot in my DVDs, every time I shoot Iím firing law enforcement rounds of 1600 feet/second slugs, or 1500/second 00 buck.
Iím not going out there running birdshot; you know if we went out there and ran birdshot #7 or #8 I could actually employ the gun much faster. My whole goal is to demonstrate and teach whatís very realistic.
