PERCUSSION CAPS.--Detonating guns have now been so long in general use, that the familiarity thus produced with the various properties and kinds of fulminating powders, ensures the very general perfection to which these invaluable auxiliaries of the shooter have attained. They are to be had, of an almost uniform excellence, at all the respectable gunmakers in town and country. WADDING.--Here again is a matter on which you will find a vast variety of opinion. Some get rid of it altogether by adopting the new system of cartridges. Upon this point I do not wish to offer any of the results of my own limited experience. I have shot with these, and with average success--a low average I admit, for I have no pretensions to the name of a crack. They are, however, worth the experiment of a trial, though I am disposed to believe the success or failure of it will much depend upon the accidental properties and effects of the materials submitted to the test. To return to the sort of wadding which may best serve those who still adhere to the old system of mere powder and shot. After enumerating the various claims of paper, hat, card, and leather, Colonel Hawker gives the preference to punched pasteboard,--the thickness to increase in the ratio of the diameter of the barrel. The best that have ever come under my notice are Cherry’s prepared waddings, suited to every calibre. They are manufactured from felt which has undergone a process that prevents the accumulation of damp after firing, and are to be procured at any gunmaker’s for the cost of the materials in ordinary use. These I do recommend, and I am sure those who accord them a trial will have no reason to regret it. They cover the powder effectually, and offer but little resistance to the shot, which is all that is required of wadding. Mr. Cherry would improve upon his invention by piercing the waddings intended to cover the shot, as it would facilitate the operation of loading, while the shooter made the distinction by carrying those for the powder in his left-hand pocket, and those for the shot in his right.
