When it comes to choosing the size of the drill bit for a specific caliber bullet, there are several factors that need to be considered. These factors include the bullet diameter, bullet weight, twist rate of the barrel, and the intended purpose of the bullet.

The most important factor to consider is the bullet diameter. The size of the drill bit used to make the hollow point in a bullet should closely match the diameter of the bullet. This is essential for achieving consistent and accurate results. Using a drill bit that is too small can result in a smaller hollow point than desired, while using a drill bit that is too large can result in an oversized hollow point.

Bullet weight is another important factor to consider. Heavier bullets typically require larger hollow points to achieve the desired expansion upon impact. This is because heavier bullets have more momentum and require more force to expand. Lighter bullets, on the other hand, may require smaller hollow points to achieve the same level of expansion.

The twist rate of the barrel is also a factor to take into account. The twist rate refers to the rate at which the rifling inside the barrel spins the bullet. Different twist rates are optimized for different bullet weights and lengths. It is important to choose a drill bit size that matches the intended bullet weight and twist rate to ensure optimal performance.

The intended purpose of the bullet should also be considered. If the bullet is intended for self-defense or hunting, a larger hollow point may be desired to maximize stopping power. On the other hand, if the bullet is intended for target shooting or competition, a smaller hollow point may be preferred for improved accuracy.

In practice, choosing the size of the drill bit for a 45 caliber bullet can be a trial and error process. It is recommended to start with a drill bit size that is slightly larger than the bullet diameter and gradually increase or decrease the size until the desired performance is achieved. It is always a good idea to perform thorough testing and analysis to ensure that the chosen drill bit size produces the desired results.

As an example, let's say you have a 45 caliber bullet with a diameter of 0.452 inches and a weight of 230 grains. The barrel of your firearm has a twist rate of 1:10, which is optimized for this bullet weight. For self-defense purposes, you want the bullet to have maximum stopping power. Based on these factors, you might start with a drill bit size of 0.460 inches and test the performance of the bullet. If the expansion is not sufficient, you could increase the drill bit size to 0.465 inches and continue testing until the desired performance is achieved.

In conclusion, choosing the size of the drill bit for a 45 caliber bullet requires careful consideration of factors such as bullet diameter, bullet weight, twist rate, and intended purpose. It is recommended to start with a slightly larger drill bit and perform thorough testing to ensure optimal performance.
