I took a Kiner clinic a few weeks ago as my shooting has been going backward for a decade and I developed a world class flinch in the process. I tried going to release trigger with no real improvements and was about to hang it up altogether until attending Phil's clinic.
Phil noticed immediately my legs were dead and my arms were pushing the gun eveywhere except to the target and I was flinching like a spring.
One of the main points Phil made in his class room chalk talk was making the gun one with you and how all the top shooters, Harlen, Leo and others rotate like turrets on a tank because they have a strong grasp on the grip and their gun is pulled in tightly not firmly into their shoulder. When I asked Phil how tight, he gave me more than a strong handshake and then we interlocked bent fingers and he pulled my arm towards his with a (very strong pull) I said, that's a death grip, it may be now but it won't be after you grow accoustomed to mounting your gun and making it one with you.
I've shot twice since his clinic and have found already eveything comes together if the gun is pulled in tightly and you have a very firm grasp on the grip, the move to the target is smoother the targets are more centered and as of now, no flinch. Thinking back when I was young and strong I always had a strong grip on my gun and is was cranked into my shoulder. As I grew older loosing strength in the process I became lazy not working at holding onto my gun and everything suffered. Doing it Phil's way at this moment is nothing but work and tiring, I have to make myself grab hold and pull in, but the payoff is more scored targets.
I have Phil to thank for reminding me the etiquette of holding and pointing a shotgun.
