Isnt that how everyone should hold every gun irrespective of calibre?
I didn't realise holding a gun was a skill, must be some interesting people out there!
Perhaps transferable skills to the hunt.
In general, my 80’s army time taught trigger hand’s elbow out laterally wingman style and the butt in shoulder pocket (or way out on the shoulder). I look back and think how “bad.“ Many years later doing civvie Uncle Sam, tactically (we) kept our head up and put the butt high and centerline as you might (certainly not even anywhere near the shoulder pocket) and always w elbows down, grasping under the barrel, all elbows pointed to respective hips. For humans, not game. I look at this as “good.”
Later the training rage became support arm out laterally from the barrel and pocketing the forend up front using your hand with the “C-cup.” When that became the vogue we trained it limitedly only for the exposure; that technique was left to our individual choice if we wished to integrate the style. I didn’t. I like my support arm elbow well bent and pointed down, and centered, too. Everything sucked in tight and centered, I guess. Also that to me is the better technique for sub and machine gun work.
Also, with rifle up, we went from walking smoothly/quickly a la Groucho-Marx style (to level the head and gun//sidearm/rifle/carbine/subgun) to just plain walking normally. I imagine these techniques can apply when walking in tight bush expecting a flush or charge. I’m always centering my rifle butt high when walking and expecting game flush. I’d probably do the same with dangerous game but never hunted DG animals.
Sniper stuff was purely focused on prone, though we did other positions of course.
In analogy, always trained handguns to use our trigger finger’s first pad (ahead of the joint about 3/4” back from fingertip) and to always use a trigger reset for shooting, including trying to do so for repetitive fast fire. Then came a vogue to “mash” the trigger finger by using the actual joint or even the front of the second pad On the trigger face! Weird. Being our choice how to “evolve” I chose to remain captain caveman with these new techniques.
I believe you just fall back to what you’re most comfortable with having done in repetitious training.
