We recommend ball brass ammo for shooting at steel and paper targets:
Frangible bullets are recommended for close up steel shooting (Not point blank with centerfire rifle rounds)
Steel core ammo isn't recommended for indoor range because it damages backstops that cost tons of money to repair. They will typically use a magnet to check for steel core ammo before enter the range.

Best AR15 Ammo For Personal Defense

Best AR15 Ammo For Hunting
With all ammo types available for the AR15. The 6.5 Grendel, 350 Ledgend and 7.62X39 are the best option for hunting deer sized game.
The 6.5 Grendel is a great choice for you if you're a recoil-sensitive shooter. Its .264 caliber and short size make it easy to fit into AR-15 rifles.
Federal makes a special bullet for hunting deer, called the Fusion, and it's a great choice. At 500 yards, it still has 588 foot-pounds of power, which is a lot more than the 62-grain .223 Rem. bullet. This extra power increases your chances of taking down the animal with just one shot.
With its ability to fire larger, heavier, and more aerodynamic bullets, the 6.5 Grendel is perfect for hunting deer-sized game. And because it has a slightly larger powder capacity, it generates more power than the .223.
7.62 X 39
The 7.62 X 39 is also a great option that carries more energy into its target as long as the target is within 300 yards. It's much cheaper than 6.5 and 350.350 Legend
The 350 Legend is a straight-walled cartridge that's great for hunting deer and medium-sized game in certain states that regulate cartridge design to reduce risk near homes.
It offers low recoil and is considered safer and legal than bottleneck cartridges. Check your state hunting laws for restrictions.

The .50 Beowulf creates a lot of energy, with a 350-grain bullet producing around 2,350 foot-pounds.
This is almost double the power of the 6.5 Grendel. But, as the distance increases, the power drops below 1,000 and the 6.5 Grendel becomes stronger. If you're hunting bear in dense brush or deer in bear territory, where the shots are usually less than 150 yards away, the .50 Beowulf is a good choice to fight against wild animals.
The .50 Beowulf has more kick than other cartridges, but the AR-15's gas system helps reduce some of the recoil. If you add a muzzle brake, it's still strong but easier to handle. This cartridge is great for hunting because of its size and power.
The bullet is half an inch wide, making a big hole in the animal after it hits. This cartridge is powerful enough to take down a bear at medium to close ranges, but you need to aim well. Not many companies make this cartridge, so you need to buy the ammo early.
Sometimes, there are special state rules that say how many bullets you can put in a magazine. Usually, you can only have five bullets in a magazine. There are lots of different kinds of magazines that are the right size.
Make sure you order one before hunting season starts so it works properly. Some companies that make guns for hunting already include the right kind of magazine with the gun, and you can also buy them as an extra thing.
Best AR15 Ammo For Precision Shooting
In order to get more out of the AR15 platform for precision shooting, we need to upgrade to a longer barrel and use a different ammo type than using the 5.56.
The .224 Valkyrie has low recoil just like the 6.5 Grendel. However, it can shoot heavier bullets up to 1,300 yards while the .223 can only shoot lighter bullets at 800 yards or less. Both are great for hunting, but the .224 is better for hitting long-range targets due to its flatter trajectory and higher ballistic coefficient.
It stays supersonic at a greater distance.
Be sure to check out some great long range scopes with precision aiming reticles to help ID targets and hit more accurately.
