Another factor influencing rate of fire is the supply of ammunition. At 50 rps (3,000 rpm), a five-second burst from an M134 Minigun would use approximately 6.3 kilograms (14 lb) of 7.62 mm ammunition; this alone would make it an impractical weapon for infantry who have to carry a reasonable supply of ammunition with them. For this and other ...
Multiple shots using rounds from the same type and batch are fired to observe how the weapon groups the shots. If a person holds the weapon and shoots it, the grouping measures the combination of the person's skill and the weapon's accuracy. [2] In shotgun shooting, the grouping is also called the pattern or "spread".
9.3×62mm: Very common big game hunting round in Scandinavia along with the 6.5×55mm, where it is used as a very versatile hunting round on anything from small and medium game with lightweight cast lead bullets to the largest European big game with heavy soft point hunting bullets. The 9.3×62mm is also very popular in the rest of Europe for ...
Time on target (TOT) is the military co-ordination of artillery fire by many weapons so that all the munitions arrive at the target at roughly the same time. The military standard for coordinating a time-on-target strike is plus or minus three seconds from the prescribed time of impact.
Thus the optimum rate of twist for this bullet should be approximately 12 inches per turn. The typical twist of .30-06 caliber rifle barrels is 10 inches per turn, accommodating heavier bullets than in this example. A different twist rate often helps explain why some bullets work better in certain rifles when fired under similar conditions.
Poppell — whose testimony started Thursday afternoon and continued Friday morning — told jurors there are two basic ways to differentiate between a real bullet and a dummy round.
The term bullet is from Early French, originating as the diminutive of the word boulle (boullet), which means "small ball". [3] Bullets are available singly (as in muzzle-loading and cap and ball firearms) [4] but are more often packaged with propellant as a cartridge ("round" of ammunition) consisting of the bullet (i.e., the projectile), [5 ...
The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.
