I can assure you that I have plenty of training by some of the best in the industry. I don't shoot nose to charging handle. That is a great trick for the untrained so they can start building some kind of consistency. You were correct in mentioning consistency but that eventually becomes specific to the individual shooter.
From the sounds of it you are probably one of those that swear you have to use only the tip of the finger on the trigger? That is a myth as well. Individual grip may not allow that to be an accurate technique.
nooo, i was referring to people who have their head floating back by the buttplate. sorry, i can't find a good pic of what i mean right now.
but with IRON sights, the further away you have your eye from the rear aperture, the smaller it gets and the harder it becomes to find the front sight thru it. i grew up shooting with globe sights, so fine tuning of the distance from the rear sight will affect the perceived size of the aperture and not seeing any crescent of light around the front sight globe is a good thing.
however, on the HKs i put my cheek against the hump at the front of the stock/back of the receiver, on the AK i put my cheek in the saddle behind the receiver, and on the AR i shoot nose to the charging handle. all three positions give consistent cheekwelds on these rifles.
on some other rifles with conventional stocks i sometimes shoot nose to thumb, again, it's a reference point.
doesn't work on some stocks or all rifles tho.
if you like being further back, and you're trained, and it works for you, that's fine. carry on.
however just because YOU are trained and keep your face back doesn't mean that everyone who keeps their face back is trained. i was simply making a generalization that many of the people who don't put their head forward are not trained.
as for finger position on the trigger, whatever works. on some guns i use the pad, on some guns i use the joint. all depends on the gun, action type, grip size and shape, and other variables. for example, what works on a 1911 with a #4 SA trigger may not work on a DAO snubbie.
now, if you're shooting with a red dot, eye relief doesn't matter, all you need to do is put the dot on target. sight alignment is no longer a problem.
