Would a projectile (arrow, bullet) with holes drilled in its length be faster and have greater range?

Actually, it is more likely to increase the relative effect of drag.

Consider equal drag forces on two objects of different mass.

The acceleration due to that force on the massive object will be less than for the less massive projectile.

The part where it would get tricky is to consider that you get more acceleration on the less massive object when you launch it as well. The problem is that drag forces scales with velocity squared. Even accounting for the extra acceleration you give the smaller mass, the fact that the drag force is both greater and causes more deceleration means that it is unlikely to be a better projectile.

You can always do the math yourself, it's not too hard as long as you're only finding drag at a point.

Drag will be higher, and the ratio of mass versus drag would become worse on both sides of the fraction.

Drag is caused by friction (and lift creation, but I would consider that to be minor, or we would not talk about projectiles but gliders). Friction is proportional to the dynamic pressure (density times speed squared, divided by two) and surface area. By drilling a hole, you increase surface area! Now some air will flow through the projectile instead of exclusively around it. If the projectile is slender, the hole will be small relative to its length and friction will slow down the air so much that the flow through this pipe-like hole will almost cease. Now the almost-blocked pipe will see a much lower flow speed and, consequently, smaller friction drag.

But still it will be best to avoid any holes at all.

Now Rick has done a simulation on a corner case: A very blunt projectile with a massive hole, moving at a not-really-bullet-like 1 m/s. Now in this case you get decent flow through the center which helps to reduce base drag. In the arrow of your question this will not work because friction losses in the long hole will not allow much mass flow, and base drag will not change much. However, boat tailing the projectile has been proven to be much more effective in reducing base drag.

There can be a use for hollow rings as projectiles. This dog toy for example.

The usefulness comes from allowed increase in stability. Projectiles are typically stabilized either by spinning them, with fins, or both. Fins work by adding drag to the tail (they get a big boost from the lift ratio but it still adds drag) Spinning doesn't add forward drag, but the rotational motion of the surface is resisted by some rotational drag that will slowly decrease the rate of spin. With lightweight projectiles, this reduction in spin can be the limiting factor for range, as once the spin rate becomes too low, the projectile will become unstable. This can occasionally be seen with flying disks when the beginning of the flight is smooth, but then the disk begins to wobble.

So where hollowing out the center come into play, is that a ring has more rotational inertia than it's solid counterpart. This allows the projectile to spin longer and therefor stay stable longer. This is one reason the aerobie flying disk has more range than a typical flying disk.

From a drag point of view, with two objects of equal volume, both sculpted to reduce drag, but one has an air-path through it, the one without the air-path will always have less drag (as long as they are both stable) This is due to the necessary increase in surface area leading to more skin friction.

However, if you're looking at two objects with the same exterior, then the one with the hole from the front to the back will sometimes have less drag. For example I just ran a quick simulation on two bullet like objects falling through air at 1m/s:

velocity field of solid object

This is the solid object and it had a drag of 0.925 mN

velocity field of object with hole

This is the solid object and it had a drag of 0.846 mN

So at first glance it seems like a hole is a good idea. However, the hole also removed mass. That means the same drag will induce a stronger deceleration, so the projectile will actually go slower and have a shorter range.

Additionally for long and narrow geometries (like an arrow) the hole actually makes the drag higher:

hollow arrow velocity field

Here the solid 60 cm long 1 cm diameter cylinder had a drag of 0.127 mN. The outside surface of the hollow version had a drag of 0.101 mN but the drag on the inside brought the total up to 0.138 mN for a net increase in drag.

In conclusion a hole can be used to add stability, but in most scenarios it will decrease the speed and range of the projectile even if it manages to decrease drag.
