No, the bullets have no effect on artillery and tanks.
Most of them do. As for bullets designed for maximum penetration on impact, hollow point and soft point cartridges are probably what you're referring to. Hollow points are more common for defensive rounds, and soft points are common hunting rounds.
Yes
Artillery rounds have a curved trajectory.
An AK-47 can put a bullet through a 1/4 inch thick part of titanium, so anything around 2 inches or thicker should stop a bullet, it depends on how powerfull the gun is, but the thicker the titanium the better, if i wanted a sheet of bulletproof titanium i would make it at least 5 inches thick if not 6 inches.

It depends strictly on the magazine. Some magazines hold 10 rounds, some hold 30 or more.
Right now, I'm using the AUG in multiplayer because it's got a great rate of fire and bullet penetration. (a few rounds shot into two people side-by-side) But you can choose any gun you want.
The MP40 utilized 9x19 Parabellums - standard 9mm rounds.
Tracer rounds are made by attaching a bit of magnesium sulfate to the rear of a bullet. This compound burns bright and creates that characteristic trail.
Nine rounds for the .357 Magnum model, eight rounds for the .41 and .44 Magnum models, seven rounds for the .440 CorBon and .50 Action Express models.
A round is another word for a bullet that has been fired or is in the weapon. For instance in the army if a soldier asked another how much ammo they have they would say "i have _____ rounds left" or if someone asked you how much you shot someone you would say "they got hit with three rounds" so its just another name for a bullet.
