Technique for shooting F Class
Glen,
I shoot with many of the best F-Class competitors in the world on a regular basis and almost everyone shoots/holds his rifle differently. You have to work out what works best for you and only you can do it. The best thing you can do; is to do everything related to your shooting; be it the ammo loading steps, to your rifle/bag setup to, to the amount of pressure you put on the rifle, the very same every time.
The cheek pressure on the rifle, the hand pressure, the shoulder pressure must be the same for every shot. Everything you do can affect the recoil pattern of the rifle and hence the grouping and impact point of your shot.
When you setup your rifle in the bags move it back and forth a few times to preload it in the bags and beat on the top of the butt to seat it down in the bag. This will reduce the settling of the rifle as you shoot.
When I shoot F-Class I have the butt in my shoulder with a fair amount of pressure, my cheek lays on the cheek piece with some pressure and my trigger hand holds the pistol grip with a light pressure so that on recoil everything stays in place. I ride the recoil is one way of putting it. Not a death grip, but I am part of the package.
Develop a routine for everything you do and stick to that routine for each and every shot you make.
Best of luck with your shooting,
Larry B.
