How much does bullet type affect .17 HMR performance?

Bullet Selection for Varmint Hunting

When selecting a bullet for varmint hunting with a .17 HMR, it’s essential to choose a varmint-style bullet with a long, pointed nose and a small diameter. Examples include the Hornady V-Max and the Winchester AccuTip. These bullets are designed to maintain their velocity and accuracy over long ranges, making them ideal for varmint hunting. For instance, the Hornady V-Max bullet weighs 17 grains and has a ballistic coefficient of 0.17, resulting in a flat trajectory and minimal drop at 100 yards.

Bullet Selection for Small Game Hunting

For small game hunting, such as rabbits and squirrels, a hollow-point bullet is often preferred. These bullets are designed to expand upon impact, providing a larger wound channel and increased stopping power. Examples include the CCI TNT and the Hornady HP. When selecting a hollow-point bullet, look for one with a large hollow point and a thick jacket to ensure reliable expansion. For instance, the CCI TNT bullet weighs 15.5 grains and has a muzzle velocity of 2,550 fps, making it suitable for small game hunting at close to medium ranges.

Ballistic Performance Considerations

When evaluating the ballistic performance of a .17 HMR rifle, consider the bullet’s weight, shape, and jacket material. Heavier bullets tend to have better penetration and expansion, while lighter bullets are more suitable for longer ranges. Additionally, consider the rifle’s barrel length and twist rate, as well as the shooter’s skill level and experience. For example, a .17 HMR rifle with a 20-inch barrel and a 1:9 twist rate can handle bullets weighing up to 20 grains, but may not be suitable for heavier bullets.
