If you are looking for rifle ammunition, you’ll most likely be faced with a lot of different terms you might not be familiar with. You’ll see things like “full metal jacket,” “grain load,” and the calibers themselves. Sometimes, the differences are minor or inconsequential. Other times, they are fairly significant. For example, the AR-15 is chambered to shoot .223 REM ammunition. That is a type of bullet that is .223 of an inch and is produced to match the specifications set out by Remington. However, it can also fire 5.56 NATO. What’s the difference?
What’s the Difference?
.223 REM and 5.56 NATO are both bullets that can be fired from a standard chambered AR-15 platform rifle. The standard difference between these two types of rifle ammunition in Los Angeles, CA is the grain load. The grain load is the amount of gunpowder put into each casing, which ultimately determines how much power the bullet has. A 5.56 rifle, such as those used by the US military, have larger chambers. That means they can handle a more powerful bullet.
A .223 chambered rifle you might buy from a US gun shop will most likely have a smaller chamber. That makes them more accurate, but they will not handle the higher pressure 5.56 as well. You should visit S Browne Supply LLC and ask about the right ammunition for you.
What Are the Numbers?
The numbers you have seen on rifle ammunition follow two paths. Ammunition made in the United States for United States rifles often have calibers that are parts of an inch. For example, a .45 caliber is .45 of an inch. Alternately, international ammunition is often in millimeters. For example, a 9mm pistol round is .38 of an inch.
Some types of ammunition are interchangeable. You will need to ask professionals about which ones are right for your firearm.
