Agreed. That is how I learned rifle and shotgun growing up, learning from all of the old comp. guys traveling around to competitions with my uncle.I think the cheapest and most cost effective "training" is just to show up at IDPA or IPSC practice sessions or matches. Most techniques can be honed there with free advice from a wide variety of better shooters than you are. Take all that info and find out what works for YOU. Attending a multi-hundred-dollar class may result in learning one specific technique from a teacher that does not work for you. And there are many techniques out there that can get the job done.
