.17 HMR Information

The .17 HMR (Hornady Magnum Rimfire) is a rimfire cartridge introduced in 2002 by Hornady. It's based on the .22 WMR case, necked down to accept a .17 caliber bullet. Here's some key information:

• Origin and Development: Developed by necking down the .22 WMR cartridge, the .17 HMR was designed to provide a flatter trajectory and greater accuracy than other rimfire cartridges.

• Performance: Known for its high velocity and flat trajectory, making it suitable for varmint hunting and target shooting at moderate ranges. Bullet weights typically range from 17 to 20 grains. See also: https://www.wikiwhat.page/kavramlar/Ballistics

• Accuracy: The .17 HMR is widely regarded as a very accurate rimfire cartridge, often exceeding the accuracy of the .22 LR at longer distances.

• Effective Range: While performance varies depending on the firearm and ammunition, the .17 HMR is typically effective out to around 150-200 yards. Factors like https://www.wikiwhat.page/kavramlar/Wind%20drift can be significant at these distances.

• Use Cases: Primarily used for varmint hunting (e.g., squirrels, prairie dogs, rabbits), target shooting, and pest control. Its flat trajectory and accuracy make it well-suited for small targets at longer ranges.

• Advantages:

  • Flat trajectory compared to other rimfire cartridges.
  • High velocity.
  • Good accuracy.
  • Relatively low recoil.

• Disadvantages:

  • More expensive than .22 LR ammunition.
  • Lighter bullet weight can be more susceptible to wind drift.
  • Not suitable for larger game.

• Common Rifles: Many manufacturers produce rifles chambered in .17 HMR, including Savage, Marlin, Ruger, and CZ.

• Ammunition Availability: .17 HMR ammunition is generally available from major ammunition manufacturers, including Hornady, CCI, and Winchester. Different bullet types are available, such as https://www.wikiwhat.page/kavramlar/Polymer%20Tip and hollow point.
