FMJ-Full metal jacket. I believe that means the bullet is jacketed all the way around; full nose on the bullet; less expanding and deeper penetrating.
Hollow Point-Center of the bullet is hollowed out so the bullet mushrooms out upon penetration.
Ball-Is a hollow point bullet with a small rubber ball in the hollow point. Gives the bullet an FMJ/full nose profile so it feeds through a semi-auto pistol better. Less jams.
I stand corrected if I am

Usually on Ball Ammo, the back side is exposed to lead. With FMJ, it's just that, the whole thing is incased in copper.
Also FMJ usually refers to rifle rounds and Ball Ammo refers to pistol rounds.

Full Metal Jacket:

Also, the terms Full Metal Jacket and Ball are usually interchangeable. Example, military 7.62x54 full metal jacket ammunition is usually referred to as 7.62 ball ammo.

FMJ is usually interchangable with 'Ball' ammo. The jacket covers the bullet from front to back, and it's not uncommon for it to be open in the back. Usually a steel core is AP (armor piercing), but 'Ball' is still used if it's standard issue. It's (was ?) common to distinguish between ball, AP, and tracer ammo. Per international law military ammo should be FMJ/non-exapnding.
HP (hollow point) is where the jacket covers the core from back to front, leaving an open tip, for either an expanding design or for match ammo. It's easier for bullet makers to control weight with a HP, so non-military match rifle ammo is usually a boat tail HP. Another type of expanding design is a soft point, where the jacket doesn't go all the way to the tip.

More questions:
9mm "Parabellum"?
Frangible Rounds?
Another side question, I recently saw a 7mm bolt-action Winchester rifle ands round type and it surprised me!
(Surprised since I never knew of that caliber and how large the round was when I saw it)
Compared to an M16 5.56mm round is the 7mm more potent?

Are you talking the round or the shell casing. The round is not that "large" but if you are talking 7mm magnum,(it will have a belt) this is a very potent round for most American game out to 400 yards. As far as being comparitively potent, yes it's far more potent than a 5.56. But compare that 7mm to some of the .458magnums and you will really see some power.
The M16 round is pretty weak in the relm of powerful ammunition, but it's intended for a completely different purpose than what a 7 mag is meant for. Humans vs. Elk!
9mm Parabellum is the full name for the common 9mm cartridge.

'Glaser' is a type of frangible round, which is often similar to shotgun pellets epoxied to form a bullet, with a case. They come apart quickly upon impact, especially at the high velocities that are often used as they're lighter than typical rounds. They're designed for moderate penetration and very high expansion, and if they do penentrate they're ranked among some of the most lethal rounds that you can use. I did say if. They were designed for use by the original sky marshals, for use on aircraft.
7mm is the diameter of the bullet. There are a number of 7mm rounds, each typically being able to handle different weight bullets at different velocities. In general the larger the case the higher the velocity. Among match bullets some of the 7mm have the highest ballistic coefficients (speling ?)available, which is a measure of how well a bullet retains velocity. The 7x57 Mauser used in the Spanish-American War led to the US developing the 1903 Springfield, and W. Bell, perhaps the most fammous elephant hunter ever, used a 7x57 with solids. He was a very good shot and had lots of nerve, preferring head shots at close range.

Visit www.winchester.com and on the right hand side you will be able to select your caliber and bullet weight. A picture will be provided along with ballistic data for each round. Interesting stuff really.
The 5.56mm (.223 caliber) was designed to provide a combination of low recoil, reasonably accurate full auto, good accuracy, light weight, and lighter weight ammo. It had some teething problems when it was issued as the Army changed the powder type, which combined with the more relaxed cleaning requirements of the M14 led to a lot of jamming. The Marines wanted better long range capability and the result was the M16A2, which seems to almost weigh as much as the M14 that it replaced. They replaced the full auto with a three round burst mode, added a heavier barrel and used a heavier bullet. Marines have reported that it's the most accurate weapon that they've used, even compared to the M14. The M14 (7.62mm NATO, which is the .308) is a premier long range weapon in a match rifle, but the M16A2 seems to be more consistent as an issue service rifle. One sees the M16 and the civilian equivalents on highpower ranges, shooting out to 600 yds, while almost none of the much talked about SKS/AK/HK rifles are seen.
The 5.56 is popular among Alaskan natives as it'll get the job done with good shot placement, ammo is cheap compared to other centerfire cartridges, and it has low recoil. I remember considering a heavy barrel AR15 for target shooting, but declined as it seemed real expensive at something like $600. That was obviously awhile ago.

Anyone heard much on the new M8?
