The correct adaptation of No. 5 or No. 6 for your particular gun is easily attained. Place in the muzzle an ordinary wadding, press it into the barrel the depth of the diameter of the shot, which should be exactly flush with the muzzle, place as many shot corns on this as you can, without having more than one distinct layer, and observe the size that best fills, in concentric rings, the whole circumference of the bore, leaving no half-spaces unfilled; note whether it be No. 5 or No. 6 shot, and keep to that size for your general shooting. Again, on other occasions you may wish to use larger shot (Nos. 4, 3, or 2); then ascertain by the same method which fills the concentric rings most perfectly: the same should be done with the smaller sizes, Nos. 8 or 9. The rationale of this proceeding is that any half-spaces are filled by shot from above pressed in upon the lower layer, disfiguring itself and those it comes into contact with; this is multiplied up to the 13 or 14 layers of which the charge is composed, and the inevitable result is that four or five pellets are pressed together until they adhere; either “balling” or leaving empty spaces in the distribution of the charge, to the injury of the gun’s shooting--a defect which may easily be obviated by attending to the instructions given above. One other point may be observed, viz., that if 1-1/4 give 15-1/2 layers of shot in concentric rings, the charge should be reduced until the rings are complete, for the half-layer will do much mischief by its unequal pressure on the layers beneath it. And it is further necessary to observe that in loading a gun, either with powder or with shot, the gun should be kept as nearly in the upright position as possible: the more upright the gun is held, the more perfectly will it be charged, and the more perfect will be its shooting. A vast number of useless changes have of late years been introduced into the construction of gunnery; they have died, however, a natural death, as they ought to have done, and have thus afforded additional evidence that sportsmen of the present day only adopt what are really improvements. Great professional reputation in a gunmaker is not now, as formerly, all that is required to command a trial of individual plans of improvement: the improvement must be self-evident; nothing being taken on trust: a _bonâ fide_ benefit to the sportsman is essential in the present day to obtain patronage.
