The PMC Bronze line of rifle ammunition is extremely popular among recreational shooters.  The reason for this is because it is available at a low price and yet still maintains excellent performance with high velocities and good accuracy. 



The projectile used in this particular PMC Bronze .223 Remington load is a 55-Grain full metal jacket projectile.  The 55-grain projectile is an an extremely popular choice in .223/5.56x45mm loads.  This projectile performs well in a variety of rifle barrel twist rates, most notable in 1:7, 1:8 and 1:9 twist rates, commonly found in AR-15 barrels.


The projectile is primarily composed of two different metals.  The jacket of the bullet is made from copper.  This heavy copper jacket encloses the lead core.  The strong, copper jacket helps to prevent expansion or deformation during the firing process, which could happen if the projectile was composed solely of softer lead.  The copper jacket also helps to prevent leading of your barrel by encapsulating the lead core.  The lead core helps to increase the total weight of the projectile.  Also the softer lead core helps to prevent ricochets by deforming one it strikes a hard object.



The projectile used in this load also has a boat-tail design.  This means that the rear portion of the projectile as a taper to it, as opposed to being squared off.  This tapered element can help to improve accuracy and may assist in giving the round superior ballistics.  This can be particularly helpful for target shooting as well as for hunting applications.



The round is a .223 Remington caliber cartridge.  This round is able to fired in barrels chambered in .223 Remington or 5.56x45mm NATO.  This also includes variations of those chambers, such as .223 Wyle, Noveske Mod 0 Chamber, etc.  The overall length of the cartridge is sufficient enough that it can be loaded into box magazines for the AR-15, such as the Magpul PMAGs, Lancer L5 magazines, as well as several other box magazines.  The projectile used in this load is 55-grains in weight and has a ballistic coefficient of 0.243.  When combined with a test rifle muzzle velocity of 3200 feet per second, this equates to 45.47 inch drop at 500 yards with a 200-yard zero.  You can also view further technical specifications.
