The .30 caliber Luger cartridge goes by several names which makes searching for it somewhat confusing. Originally it was named 7.65 Luger Winchester markets it under the name .30 Luger with a 93 grain bullet. Sako of Finland also markets the round with a 92 grain bullet. While not usually available in a WalMart one can find the round in a larger dedicated gunshop in the United States.

Gun shops, gun shows

What does the owner's manual say?

It should be marked either on the receiver or barrel

Mine is marked .410 3" chamber, and it works extremely well with WInchester Super X ammo

It depends on the pistol, but mostly it depends on the magazine. Some what you would call "regular" 9mm magazines hold as few as 6, some hold as many as 18 or 20, however, you can get magazines for regular service pistols that hold as many as 30 or more. I have a 33 round magazine that fits my Sig P226.

You compare the rifling marks on the bullet to the rifling in the barrel. You can also compare the firing pin mark on the primer to the firing pin on the gun.

It can use either 44 magnum or 44 special

If it came from the factory with both cylinders, you shoot the ammo the cylinder was designed for.

In 1845, Flobert of paris invented the .22 short cartridge. Originally for self protection, the caliber has exploded in popularity and uses.

No, but a 38 special will work in a 357

Remove the head or destroy the brain

Maybe about 20% more than standard shells.

If you do an internet search, you will get a couple of different hits. For the most part it is made in batches and not all vendors have it at all times.

As a general rule, NO, NO, NO!!!!

Colt .38 New Police was the Colt name for .38 S&W. Same ammo.

A bit over 3,000 yards, depending on the rifle. Please note tat is NOT the effective, usable range, simply the maximum distance the bullet can travel over a relatively flat surface (with no accuracy)

About 2,000 yards. No accuracy, just maximum range, when fired at about a 34 degree angle. Will vary depending on rifle and exact loading of the cartridge.

There have to be at least 20 different shells in current production that can be loaded with a .30 caliber bullet.
If you look at the barrel of the gun, the chambering should be stamped into the metal.

Yes. There is a gun called the M-134 minigun that shoots approx. 300 rounds per second.

460 meters per second is the fastest in testing. this is equivalent to 1096.101 mph

The .40 caliber bullet is a little larger in diameter and is a little heavier (under most circumstances). The .40 will usually have more powder, velocity, and muzzle energy. Also, the .40 is designed for use in a semi-automatic and the .38 is a revolver cartridge.

Round accuracy is improved by spinning the projectile. This is achieved by spiral grooves running down the length of the barrel.

This spin strengthens the momentum of the bullet along its trajectory and in part creating a stable vortex around the projectile.

Along its flight air friction slows and weakens the stable momentum of the projectile. Random environmental factors such as wind, particles, varying air pressure, then act on the bullet sending it off course.

Yet the weapon itself can be a cause of tumble also. Uneven cartridge and wear of the barrel allow the explosive forces and gasses to cause tumbling. That's why you can strip a weapon and change the barrel.

So in most respects the bullet begins to tumble as soon as it exits the barrel. A good indicator of when the tumble effects accuracy is the 'effective range' of a caliber. This a combination of unacceptable accuracy and ineffectual damage to a target. IE beyond the maximum range you can get hit and have nothing more than a minor bruise.

Ammuntion that has a thin jacket of metal (copper for example) that encloses the lead projectile.

Looking at 300 Weatherby and 300 Win. Cartridge images in this site:

Looks like they are two different sizes.
