for the book I am working on.
(I figured something was up. Its about time)
#1 Describe what portion of the trigger finger touches the trigger. (My personal description is 'the trigger should be placed directly under the cuticle of the trigger finger'). Agree?
Agree. (after some anatomic study of my thumb)
#2 Describe the position and tension applied by the thumb.
I'm a stickler on this one. I build my own thumb holes with palm swells for both hands. When finished it amazes me how different the swells are on each side. How does one describe position and tension? Think of testing 'doneness' of a grilled steak w/pressure. I'm right handed. My right thumb muscle is medium well and the left is medium rare. It takes great attention to that difference to achieve similar accuracy when switching sides. Thumb tension is important!
My other LR rifle is one sided (lefty) and is designed with a straight/vertical pistol grip w/swell. The swell is the "indexer" for consistent thumb position. The forearm and elbow follow the thumb as indexed by the grip and swell.
#3 Describe the position and tension applied by the bottom three fingers.
With the vertical pistol grips and thumb holes w/vertical pistol grips, position of the bottom finger is against the small ridge that I build in to the grip with the thumb gently fitted into the thumb hole or thumb groove and very delicate three finger pressure kind of like gently squeezing a with a gentle straight pull back to the shoulder. Note, all of this after checking the "natural POI" that is, none of this moves the natural point of aim. If it does then the shot is being forced.
And, if your pinky is ever under the pistol grip, you have problems, IMO.
#4 Describe the importance of follow-through and how long you consciously remain on the trigger after the shot.
My next expected experience after the trigger clicks is seeing the impact of the bullet. What ever I do to achieve this experience must be follow-through. Mostly I concentrate on not blinking at the shot. I am on the trigger until its time to reload.
#5 Do you try to cup your palm if your stock does not have a palm swell? Some instructors teach that you should have "air in your palm", no direct contract with the pistol grip. Comments.
My opinion is that since one can't 'feel' air' is what drove the development of the palm swell. I have an very hard time coming to grips with a sporter stock.
#6 Do you practice trigger control by dry-firing?
Roger that, big time? I do way more dry firing that I do actual shooting. I have a 1200yd dry firing range in my back yard. That's where I imagine many different shots under all kinds of conditions. I've made some wonderful shots well beyond 1.2k with an empty 222. because it has the same well adjusted trigger as my LR guns.
