Bulgaria. Anciently Mœsia, now part of European Turkey. The Bulgarians were a Slavonian tribe, who harassed the Eastern empire and Italy from 499 to 678, when they established a kingdom. They defeated Justinian II., 687; but were subdued, after several conflicts, by the emperor Basil in 1018. After defeating them in 1014, having taken 15,000 Bulgarian prisoners, he caused their eyes to be put out, leaving one eye only to every hundredth man, to enable him to conduct his countrymen home. The kingdom was re-established in 1086; but after many changes, was annexed to the Ottoman empire, 1396.

Bull. A fort which the English possessed in Canada, and which constituted one of their military depots; it was captured by the French, March 27, 1756.

Bulletin. A brief statement of facts respecting some passing events, as military operations, etc.

Bullet-mold. An implement containing a cavity of the proper shape into which lead is poured to form a bullet.

Bullet-proof. Capable of resisting the force of a bullet.

Bullets. Are projectiles of lead to be discharged from various kinds of small-arms. The first bullets used were round, and were designated by the number weighing one pound. The sizes employed were very large. Until quite recently the round ball still held its place with rifles and smooth-bores. Various devices were used for making it take the grooves of the rifle,—a guard-patch being among the best. (See [Small-arms].) It was with this that the early settlers of America won their reputation as marksmen. Robins, in 1742, showed the superiority of the conical form, but it was not till about 1840 that round balls were generally discarded. The conical bullet was often used in grooves with an increasing twist, and gave wonderfully accurate results at short range. For long ranges, long bullets are necessary, and these require uniform twists, which are now generally used in military arms. Various forms of the elongated bullets were used. Most of these bullets had an expansive base, either hollow or plugged with wood; the design being to force the soft lead outward, so as to cause it to fit the grooves of the rifle, and thus give the bullet a rotation around its long axis during the motion forward. (See [Small-arms].) This rotation, as is well known, increases the range and precision. Bullets were formerly cast, but now they are more frequently stamped in steel dies, and, as in breech-loading arms, the bullet takes the grooves by compression; the exploding base is omitted. The form of bullet now used in military arms is the cylindrical conoidal. The tendency recently has been to reduce the caliber. (See [Projectiles].) Copper bullets are used by the Circassians. Bullets of stone were used in 1514; iron ones are mentioned in the Fœdera, 1550, and leaden ones were made before the close of the 16th century.

Bullets, Explosive. Oblong bullets carrying a percussion-cap on the front end and sometimes containing a small charge of powder in a cavity, used to blow up caissons and magazines. There is a strong sentiment against the use of these bullets in firing at troops.

Bullets, Express-. An explosive bullet of great killing power, used in hunting large game. It is of large caliber but quite light, being much shorter than the ordinary rifle-bullet. A cylindrical cavity bored in at the point carries a small metallic cartridge-case filled with powder. It is fired with a large charge of powder, which, owing to its lack of weight, gives it a high initial velocity and a very flat trajectory up to about 200 yards, obviating the necessity for an elevating sight. The Winchester Express-bullet (a good type of those made in America) has a caliber of .50, weighs 300 grains, and is fired with 95 grains of powder, giving an initial velocity of 1640 feet. It is made of pure lead, the softness of which increases its deadliness. The shock from this bullet will bring down the largest game. See [Express-Rifle].

Bullets, Grooved. Bullets having grooves, or cannelures. These grooves were originally used to increase the relative resistance of the air on the rear of the bullet, thus assisting the rotation in keeping the point to the front. In muzzle-loading arms they also increased the setting up of the bullet to take the grooves. They are now used to hold the lubricant, and to facilitate the swaging action of the grooves and lands in breech-loading guns. For the other form of modern bullets, see [Bullets, Patched].

Bullets, Patched. One of the forms of modern rifle-bullets. The bullet has wrapped around its cylindrical portion a layer of thin paper called the patch. The bullet is perfectly smooth. The other form has grooves, or cannelures. (See [Bullets, Grooved].) The lubricant for the patched bullet is a greased wad or disk of wax, placed between powder and bullet. The [grooved bullet], carrying its own lubricant, is best adapted to shallow lands and grooves. The patched bullet to sharp lands. The grooved bullet would seem to be the best for military service, as the cartridge-case can be tightly crimped upon it, making the case waterproof. For very long range the best shooting has been done with patched bullets.
