Rifle Stocks in general.
Rifle stocks are the simple yet ergonomically complicated means by which we can hold onto the barrelled action and direct the bullet to a desired point of impact, and so the better the stock is suited to the particular hunter, the greater the degree of certainty there is that the bullet will get to the intended target impact point. While this may seem a simplistic statment, it is anything but, as there are almost an infinite number of variations of the rifle stock, from the purest hunting designs to the specialist target and benchrest items made from the traditional wood's through to laminates of wood or layers of spaceage carbon fibres with various resins plus fiberglass either solid or over hollow core or foam base, through aluminium and combinations of one or more of these materials.
Leaving aside all the specialised rifle uses and stock materials, the hunting rifle in its more traditional form will be the focus of this piece.
What distuingishes a good hunting stock from the myriad of poor to average factory stocks( and many so called custom stocks) is for the hunter to able to throw the rifle to his (or her) shoulder and imediatly have the butt tuck into the shoulder pocket with hands comfortably griping the wrist and forearm and the eye alligned with the sights. A properly balanced rifle will have a very large degree of influence in how the rifle comes to the shoulder and onto target with a correspondingly important part to play in how pointable it may be and how steady it sits in hand. The metal work as far as the barrel contour which effects weight and balance will be explored elsewhere but does contribute to the rifle's balance, pointability, and tracking virtues ( or otherwise) so cant be entirely dismissed when the traits of a good hunting rifle stock are being discussed. There should be no adjusting of posture or position and the finger should fall naturally, without stretching or cramping, to the triger as the target is comfirmed and the shot is ready to be released. Any adjustment of body or rifle will naturally effect the initial aim point and inevitably effect the accuracy of the shot. It is the hunters responsibility to identify the target, (LEAVING NO DOUBT) before the rifle is lifted and he should already be looking at the desired point of impact when the rifle is raised and be comfortably and strategically alligned with the sights allowing him to be imediatly ready to release the shot. Without getting into shooting technicalities, it is a given fact that the first few seconds of a rifles hold on target are the steadiest when shooting off hand (with no external support) so it is naturally best to have a rifle stock that gives the hunter the imediate and natural positioning of the body and the rifle so as to take advantage of this. The longer a hunter holds the rifle in the un-suported aiming position while trying to get comfortable with any aspect of the stock design, then his chances of a sucessfull shot diminish quite rapidly. A hunter who uses an external suport for the rifle, (and he would do this for a longer shot at an undisturbed animal especially if he can not stalk closer) whether it be a a sling aid or resting on a day pack, the side of a tree, a natural ground feature or a set of shooting sticks can often be well suited by a stock that is less than a perfect "fit" simply because he has time to adjust to the position. However, having said that, if a rifle stock is being made for a stalking hunter, and we all like to think of ourselves as stalking hunters, then the better the rifle stock is suited to the individual hunter then the probaility of a sucesfull hunt if a desirable animal is sudenly encountered is so much higher. This is the prime reason that hunters have had custom stocks made that fitted them properly, rather than taking one off the rack that is designed for everybody but rarely fits anyone other than with the wonderfull adaptability of our body.
A rifle stock has not only to afford the hunter with a comfortable device to hold onto while aiming the barrelled action, but should also hold the barrelled action in a non movable and non stressed position so that there are no external factors that efect the point of impact for the bullet. This is another area that mass produced stocks can not always be relied on to do and so the need for a custom stock arises, or at the least customising of the factory stock to better acomplish the necessary primary function in a reliable manner.
This can bring about a lengthy discussion on what a custom stock actually is but for the purposes of this exercise I will define a custom stock as one that is made with the particular hunters body shape and hunting style in mind, from a billet or blank of well dried and stable stock wood.

Walnut species.
The walnut trees that have originated in Persia came to England via the early Romans because the nut was so highly prised.The thin shelled walnut, Juglans Regia is Persian or common walnut and is also known as English walnut because of the English sailors who then spread it round the world on thier travels and so it is also known as Royal, Circassian, French, Turkish and by the place names of many other areas it has been propogated with the soil types, climate and growing conditions of many places in the new world like New Zealand and Australia producing some exceptional stockwood blanks.
American black walnut or claro is another major walnut species used for stockwood along with the English - American black walnut hybrid which is known as Bastogne from bastard walnut.
English walnut is generally known to be hard and is often thought to be more easily worked but the growing conditions have an enormous effect of the grain structure and colour, from golds through to chocolates with mineral streaking of greens and blacks, marble cake, mottling, feathered crotch, fiddleback being some of the many grain types and colourings which influences desirability and therefore price. Black and Bastogne are generally said to have a shorter and more chip prone grain structure which can make the use of English walnut and its derivitives less problematic when checkering and other finisheing touches are being atended to.
Log cuts.
The cutting of a walnut tree to get the best from the available wood is a most thought provoking process for the sawyers. There is much study of the tree to asertain where to make the initial cuts as the difference between cutting it right and just citting it can be many thousands of dollars worth of gunstocks, either superb blanks bringing out the very best the log has to offer against getting more blanks that have much less appeal and subsequent value. Logs that produce the most spectacular blanks have large root structures and heavy branches and sometimes forked trunks where the grain can have the most spectacular patterns.
