Re: recoil managment and adj buttplate?
Specifically, about the adjustable butt, it does many things. It can help get proper eye relief without goose necking or turtle necking, which would undermine the position; and, it can complement adjustments you have made to the adjustable comb, if you have one. But, most importantly, the butt plate can be canted to allow for the rifle to be laid square or level to the target, without being forced by muscle into that condition. That's to say, you can use the adjustable butt to have a muscularly relaxed (comfortable) position.
Now, about the word comfort, in target shooting it's defined as being relaxed. Relaxed means to have minimized muscular tension. This is important since any muscle tension is difficult, even with motor memory, to maintain through follow through, or to repeat from shot to shot. When you have muscle tension there is movement since muscle cannot transfer the stability of the ground into the position. Even minuscule movement can be a problem, shot to shot, or with strings of fire as the error it inspires is angular, its effect increasing with distance. Of course, with any tension, wobble will be present too, although this is not much of a problem in that wobble error is not angular.
Most new shooters complain that they cannot get comfortable, or when they are comfortable, the position cannot be adjusted for the desired target/sight relationship. For sure, there is physical, as well as mental pain learning how to shoot. Some folks do not have the discipline, interest, or willingness to work through the pain, that's to say, they don't practice because they don't believe better results will come from the practice, or they just really don't care to do the work necessary to become an extraordinary shooter. Those that are motivated, however, will, through the mental and physical pain, at some point, get the accolades, certifications, distinctions, recognitions and other rewards that they seek.
