Armor-piercing (AP): A hard bullet made from steel or tungsten alloys in a pointed shape typically covered by a thin layer of lead and or a copper or brass jacket. The lead and jacket are intended to prevent barrel wear from the hard-core materials. AP bullets are sometimes less effective on unarmored targets than FMJ bullets are.

Benchrest shooters attempt to achieve the ultimate in rifle precision; records for single 910 metres (1,000 yd), ten-shot groups are as small as 76 millimetres (3 in) (84 μRad), the 550 metres (600 yd) record for a single five-shot group is 17.8 millimetres (0.699 in) (32 μRad) (there are no ten-shot competitions at 600 yards), while 180 ...
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length.

A smart bullet is a bullet that is able to do something other than simply follow its given trajectory, such as turning, changing speed or sending data. Such a projectile may be fired from a precision-guided firearm capable of programming its behavior. It is a miniaturized type of precision-guided munition.
Precision-guided small arms prototypes have been developed which use a laser designator to guide an electronically actuated bullet to a target. [8] Another system in development uses a laser range finder to trigger an explosive small arms shell in proximity to a target. As of 2009, the U.S. Army has plans to use such devices in the future.
