[1] Typically, many rifles use thread ...
Note: Use of this table for estimating bullet masses for historical large-bore rifles is limited, as this table assumes the use of round ball, rather than conical bullets; for example, a typical 4-bore rifle from circa 1880 used a 2,000-grain (4.57 oz; 129.60 g) bullet, or sometimes slightly heavier, rather than using a 4-ounce (110 g) round ...

While there are many forms of rifle sight, they all permit the shooter to set the angle between the bore of the rifle and the line of sight (LOS) to the target. Figure 2 illustrates the relationship between the LOS and bore angle. Figure 2: Illustration of a Rifle Showing Line of Sight and Bore Angle.
Traditional bolt hunting rifles usually have had the optical center of about 38 mm (1.5 in) above the bore, while AR-type rifles and modern bolt-action rifles usually have their optical center about 68 mm (2.7 in) above the bore. [1] On firearms with a picatinny rail, the distance from the bore to the optical axis can be divided into distance ...
