no they are not
Well... In the sense that many bullets are solid lead, no, they can't be picked up by a magnet. However, many are either steel jacketed (i.e thin outer layer of steel around a lead core), or, in certain cases, are steel cored, these bullets can be picket up by a magnet.
Now, if the question was whether the bullet itself carried a magnetic charge (and, thus, acted like a magnet), the above answer is certainly true: NO, bullets are not magnetic in and of themselves.
Modern day bullets are not generally magnetic, as they are typically made of lead or copper alloys. However, some bullets may have magnetic properties if they are made with a steel or iron core.

Fictional gun that uses magnetic fields to propel bullets.
Not really. Lead wheelweights can make decent bullets for modern day firearms. However, muzzle loading firearms have very shallow rifling, and need VERY soft lead bullets. Wheelweights are just too hard.
A Jedi would win, lightsabers can't deflect modern bullets but they easily block the bullets from hitting them. Also Jedi have the force so they could send modern soldiers flying.
it gives you more bullets

No. An antique bullet is 100 years old. That is the meaning of "antique". But they can make modern bullets to fit and antique pistol.
Shoot all of your bullets
Originally, chalkboards were made of slate stone and were not magnetic. Some modern chalkboards today are magnetic. Also growing in popularity is the whiteboard, some of which are also magnetic.
Bullets are generally made of lead, with or without a jacket of gilding metal. Those are not affected by a magnetic field- only ferro-magnetic metals such as steel and iron are attacted to a magnet. And the magnet would be the size of a large truck, and needs it's own powerplant to operate it. Sorry- what looks good in the movies, and what works in real life are sometimes quite different.
Most modern guns DO fire bullets that break the sound barrier. That is, their bullets travel faster than the speed of sound when they are fired.
