Ammunition

yes, and not easily reloadable.

Not without some adapter device.

The M249 is typically fed from a belt... 100 round "nutsacks" and 200 round plastic drums are often used. It can also be magazine fed from STANAG 4179 magazines (the type used in the M16 and several other rifles). Those can be whatever capacity they're manufactured for, but 30 rounds is typical.

The MP5 submachine gun typically uses the 9x19mm Parabellum cartridge. This caliber is known for its reliability and effectiveness in close-quarters combat. The MP5 is designed to accommodate various types of 9mm ammunition, including full metal jacket (FMJ) and hollow point rounds.

7.62x63 (.30-06) with M2 ball and 7.62x51 Special Ball were both used by the USMC in Vietnam.

Although both can, explosive material represents a projection hazard by producing shrapnel on impact with a hard object. So, if launching explosive material, be careful. wouldn't want shrapnel to cut into your body!

Depends on the loading used for the cartridge. These are pretty fast, ranging from about 3500 fps to 4200 fps. Lighter bullets can be driven to higher speeds.

.38 spl will shoot without problems from an 1892 Winchester that is chambered for .357 The .38 spl develops less pressure than the .357, and it the same diameter of bullet and casing

You may have a problem however with the .38 spl cartridges feeding properly from the magazine into the chamber. That is because the .38 specials are shorter than the .357 cartridges that the rifle was designed for.

No. Only shoot the caliber printed on the barrel.

Not a term used in dealing with ammunition. The US military uses 10 classes of supplies- and all ammunition and explosives are class V (five). Please repost your question with additional information, we will try to answer it. If your question involves a game, it may be a made up term with no real life meaning.

It depends on what you mean, but very generally speaking, there is handgun ammo, rifle ammo, and artillery ammo.

Most of the time it is 50. Some of the self defence ammo comes in packaging of 25 or 20.

Expanding Full Metal Jacket

Full Metal jacket.

As many as you can fit- but you cannot hunt with a gun that will hold more than 3.

The grooves in the barrel.

No. They are a lead bullet with a jacket of copper/ nickel alloy.

Yes

This for firearm saftey or somethin..... K the parts of a shotgun shell are the gunpowder primer casing and the bbs or slug

Yes the mags work with both ammos. You can not tell the difference in the two by looking at them.

No. Only use what is stamped on the barrel.

Yes, I have seen it done. Ammo has a long shelf life but it will protect it in humid conditions.

Sure. It is not really necessary but it would help in extreme humid conditions.

If you mean can you fire non plus P ammo in a gun rated for plus P, yes, you can safely do that as long as it is the correct caliber.

A round is a cartridge made up of the case, primer, powder and bullet. The bullet is the projectile that leaves the gun. There is only one bullet in a round.
