Let’s get into the more pointy ones:

This, dear readers, is the dreaded Weapon of War Assault Rifle Boolet. It is pointy, and is (gasp!) .22 caliber*. Actual identification is 5.56 NATO, with the civilian version known as .223 Remington.
*Ok, I pulled a fast one. The Ubiquitous .22 Long Rifle is .222 inches in diameter; the almost as ubiquitous .223 Remington is .224 inches in diameter. The first is usually a 40 grain weight, while the second was originally 55 grains, but has put on weight in recent years, at 62 grains or even higher. Also, the first runs around 1100 fps while the second is around 3000 fps.
All things considered, the .223/5.56 is a tiny bullet, but it goes very fast. So, F = MV. It gets its increased F from cranking up the V. Is it a “high-powered” round? Eh, no. Its philosophy of use is “wounds pretty well” and takes combatants out of the fight. It’s also small and light so a lot of rounds can be carried. I recall that 8 standard capacity 30 round magazines is basic load out.
Back to bullet types, the military uses FMJ (Full Metal Jacket) rounds – something about some Convention in Geneva – as depicted on the left. But there are a ton of other configurations. The round on the right is FMJHP. By now you know that means Hollow Point.
