Re: Rifle stock or Rifle scope which is better?
The length of pull on a rifle will vary, infinitely, depending on your hunting attire. Shirt sleeves offer one length of pull, a heavy jacket in the winter offers something else. The type of clothing will also affect where the rifle butt contacts the shoulder. Some shooters rely on stocks with adjustable butt plate assemblies (some are pretty exotic) to accommodate every need in that regard. There's a guy in California (Recoilless Engineering) who makes custom butt plate assemblies for just that reason.
I'm not wealthy enough to do that so I make adjustments as necessary and I practice at the range with those factors in mind, often adding/removing coats, jackets, etc. to get familiar with the equipment.
Some rifle stocks have a straight comb, others have an angled or "dropped" comb. Some have a pistol grip, some don't. The toe of the butt can be extended or recessed, depending on design and the forearm can be wide or narrow, also a factor of design and intended application.
The height of the scope, eye relief adjustment (and consistency in how the shooter comes onto the rifle when aiming) are all factors that come into play when mating a scope to a particular rifle.
I guess you could say that, bottom line, it's up to the shooter to do his/her homework when selecting rifle/scope combinations and to practice. I was instructing a young shooter at the range a few weeks ago and found he was fighting the rifle to align the sights on target. I told him that the rifle was not in charge of the session; that he was in charge. He needed to make sure he was comfortable and avoid putting stresses into the hold on target. Didn't take long for his score to improve.
I have a great woman, fantastic kids, a warm place to sleep and an accurate rifle. Life is good ..............
