.17 Rimfire Rifle Accuracy Test Results
By the Guns and Shooting Online Staff
Here at Guns and Shooting Online we have had the opportunity to review a number of .17 caliber rimfire rifles, and we are continuing to do so. We believe that the .17 HMR cartridge is the best thing that has come along for the recreational shooter in about 50 years, and we review .17 HMR rifles whenever possible.
In the course of our rifle reviews we ordinarily test for accuracy using at least four brands of ammunition and tabulate the results. This concludes with an average overall group size for all types of ammunition. Typically, groups with each rifle are fired for record by three or four Guns and Shooting Online staffers.
The 17 HMR loads we use include ammunition from CCI with 17 grain TNT bullet, Federal Premium with 17 grain TNT bullet, Federal Premium with 17 grain V-MAX bullet, Hornady with 17 grain V-MAX bullet, Remington Premier with 17 grain AccuTip-V bullet, and Winchester Supreme with 17 grain V-MAX bullet. All brands claim a muzzle velocity (MV) of 2525-2550 fps and in our chronograph testing actually delivered average MVs of 2550-2650 fps, depending on the load. (See the article "Compared: .17 HMR Varmint Ammunition" for more details about .17 HMR ammo.) Our .17 M2 ammunition is limited to Hornady brand using the 17 grain V-MAX bullet at an advertised MV of 2100 fps.
.17 rimfire rifles are normally tested with a good quality telescopic sight set at a magnification of 9 power or higher. All recorded groups are fired from a Caldwell Lead Sled rifle rest sitting on a solid bench rest at an outdoor rifle range. These are 5-shot groups fired at 100 yard targets.
This steadily mounting accumulation of data makes the following list possible. We will continue to update this list as new rifles are reviewed and additional data becomes available. Following are the Average Overall Group Size test results for the various .17 caliber rimfire rifles reviewed by Guns and Shooting Online (measured in inches).
AVERAGE OVERALL GROUP SIZE TEST RESULTS
Remember, the above accuracy results are averages with all brands of ammunition tested. If the rifles are compared based on the average group size achieved with their favored brand of ammo the results are as follows.
