Bullet security cameras are not shaped like rifle bullets but are based upon the design of the bullets with similar aerodynamic design being used by both products.
A bullet camera is a very small bullet shaped camera commonly used in surveillance. There are many sites offering this type of product including Amazon, Chasecam and Security Camera Warehouse.
Bullet-shaped
Any other shaped bullet could cause feed jams based on the ammunition not being in the right orientation with respect to the chamber and barrel. With cylindrical bullets, the orientation of the round doesn't matter. A matter of practical convenience.
Bullets in the US Civil War were actually some of the most technologically advanced of their time. Confederate bullets, while not as standardized as Union bullets, are often shaped as cylinders with a conical top section and a concave base. Less common, but still used occasionally, are round led balls.
If the bullet is not ball shaped, but conical (shaped like a missile or modern bullet), and it is pure lead (not copper jacketed) then it is most likely not prior to 1862; If it's jacketed probably not prior to 1871. Location of discovery will identify the bullet further (a battlefield or hunter's bullet). Cartridges Cartridges are marked on the bottom that can give a clue as to where it was produced. I once had some 8mm Mauser bullets in a box that I thought was German origin but they were actually Belgium. One clue was the color bands around the top that indicated armor-piercing. These color bands, if present, can also be helpful in identifying them.
The "bullet" shape is called a Gothic arch. It is the evolution of the Romanesque arch which is just a semicircle, and has a number of structural advantages.
because the manufactures are dumb
because his hair and his head were shaped like a bullet
Instead of a pointed tip, the tip of the bullet is a somewhat cone shaped hollow.
WC means wadcutter. The bullet is shaped like a soup cap- flat ends- made to clip a clean hole in a paper target. These are USUALLY fired from revolvers- but there are a few auto pistols designed to shoot them.
They are not shaped like cones, but their shape makes them more aerodynamic which increases flight speed and distance.
In most cases, however some bullets have two blunt ends. Typically, the blunt end is inside the cartridge and the pointed end is the first end out of the gun barrel (the business end). Reversing this protocal, results in a blunt end-first bullet. Blunt end-first bullets were used in World War I by the Germans primarily to pierce the armor of the British Mark I tank and against French infantry. These bullets were usually modified in the field, and were generally frowned upon by German command. The soldier would reverse the bullet, placing the pointed end and more propellent (powder) into the cartridge. If the bullet failed to pierce the tank armor, it sprayed shrapnel killing tank occupents or surrounding infantry. German infantry did not like these types of bullets because they would damage the gun or cause injury to the soldier.
