The first thing that comes to mind when one thinks of hunting is the ammo to be used. everyone has their preferences. But every ammo is quite different from others so while choosing your ammo one must keep certain things in mind like stopping power or ballistic. The two most commonly used ammo in hunting is 9mm and 5.56 ammo. Most people are generally confused between the two. Here we are going to compare the two and tell how they are different and which one is to be used in which hunting.

TECHNICALS
The 9mm Parabellum weighs 124 grains of avoirdupois, starting at speed of 1,200 feet per second. This makes it similar in ballistics to a heavy .357 magnum load, and for a handgun round, this is hot.
The actual muzzle departure velocity for 9mm rounds is approximately 4000-foot pounds, which technically suits handgun usage.
Bullets for the 5.56 NATO cartridges weigh 62 grains and will leave the muzzle at speeds of 3,200 fps. As the main standard NATO rounds, the 5.56 vs. 9mm are also measured by length as well as calibre (width). The cartridges have the designations 5.56x45mm and 9x19mm, meaning there’s a lot more room for powder in the rifle round.

9MM
A single shot of a 9mm (the equivalent of a cal. 35, pretty close to a cal. 38) hitting a big animal like a horse, cow, tiger, lion, gorilla, etc. is most likely to take it down. where you hit the target plays a role too. But if you hit the target at the right area you are more likely to succeed with 9mm.
A 9mm is very accurate up to 100 yards but carries energy pretty well only up to 25 yards. a 9mm will kill anything with 1 or 2 shots.
The pros of using a 9mm: accurate from the first shot to final follow-up shot at close range; quick follow-up ability; accurate at close range in the hands of a variety of shooters, ranging in experience and stature; balanced between small and light and great ballistics; a huge variety of ammunition to choose from.
The cons of using a 9mm: not a legal hunting firearm in some places; not a lot of energy or expansion in comparison to dedicated hunting rounds; the effective range is limited; shot placement must be flawless due to lower energy and expansion characteristics (imagine doing this under duress); there are so many other greater options out there for killing animals than 9mm.

5.56MM
5.56 is military grade ammo. The military-grade 5.56 base also has a crimp around the primer pocket. The 5.56 has a higher pressure measuring at 58,000 psi. The bullet drop on the 5.56 over a range of 500 yards is 54.2 inches. The start sees the bullet drop a little to about 1.75 inches and maintains this height up to 300 yards where it drops a further 8.3 inches. At 400 yards out, the drop is 24.56 with the 500-yard mark, making for the 54.2 inches drop.

5.56 NATO Dimensions
The 5.56 bullets measure 2.260 inches in overall length with the case measuring 1.760 inches. The bullet has a diameter of 0.224 with the neck measuring 0.253 in diameter.
The base of the bullet has a diameter of 0.377 inches. The case capacity for packing firing powder on the 5.56 is 28.5 gr. The bullet packs a pressure of up to 54,114 psi.
Their relatively flat trajectories make them ideal for varmints like prairie dogs and gophers as well as small predators like coyotes and foxes.1-855-536-8637 https://www.foundryoutdoors.com/collections/5-56x45-ammo-ar-15
