Everything You Need to Know About Ammo
For some gun enthusiasts, learning about myriad types of ammo may add to their love of firearms. Others, such as forensic experts, military historians, or those with a career in law enforcement, may need to learn about different types of ammo for their job. Whether you’re learning about ammo for the first time, or you’re a seasoned expert looking for new information; everything you need can be found at Ammo.org.
Quality
If there’s one thing you should be willing to spend a little extra on in order to ensure reliability, it’s your ammo. Whether purchasing online or in a local store, evaluate all the factors before deciding to buy. Cheapest isn’t necessarily the best option; accuracy is is a key element in choosing a bullet. Oftentimes, the less expensive brands will sacrifice accuracy in order to save money, which will end up costing you more in volume to make up for all your missed shots. Trying to pinch a penny on bullets in the short term will almost certainly end up costing you more in the long run.
Surplus
If you want to save money on your munitions without sacrificing quality, consider a surplus store. When a soldier is discharged at the end of his military service, all his weapons and ammo are reclaimed by the government. After the end of WWII, massive amounts of leftover military supplies were imported into the U.S to be sold as a result of this practice. Military surplus stores have sprung up everywhere to unload these high-grade goods; surplus supply can often be much less expensive than big box sporting goods stores.
Accuracy
Of course, everyone wants the most accurate choice of ammunition for their shooting, depending on preference and shooting goals.
●     Long-nosed bullets have a high rate of accuracy with a very flat trajectory.
●     Round-nosed bullets have an arched trajectory, but can also be quite accurate. 
●     Boat-tail bullets are very popular for their high accuracy, and are particularly preferred for matches and shooting contests.
Ballistics 
Another factor to consider before purchasing is ballistics. A bullet which maintains its initial velocity all the way to its target is an efficient bullet, with an impact that retains all of its high energy. Long, sleek boat-tail bullets typically rank highest in both accuracy and ballistic efficiency. The bullet’s impact performance, or terminal performance, should also be taken into consideration. A bullet which explodes upon impact will create a larger wound, but it has to penetrate unbroken. Finding a balance between the two is key.
Calibers
Air guns and BB guns both will use .177 caliber bullets, and either choice is a great way to start kids out, both for learning to shoot and for learning about gun safety. For small arms, the range of calibers runs from .17 to .50. The lower caliber bullets will be smaller and faster than the larger caliber bullets. The .38 caliber, used in 357 revolvers, is o
