Hornady technicians will continue to add Hornady projectiles and other bullet brands to the database. Testing is time-consuming, but rest assured, there will be more projectiles added to the library.

The size of the specific firearm chamber, throat dimensions, seating depth, bullet profile, propellant variances and crimping depth can all contribute to variations in load data. The data found in the Hornady loading manual represents actual results derived in the Hornady Ballistics Laboratory. Hornady recommends that reloaders... Continue Reading

Exact velocities can't be calculated because variables associated with individual chambers and/or barrels affect velocity, but on average, velocity gains or losses will be approximately 25 to 35 feet per second per inch of barrel difference. But that hold true for every load or every gun. To truly measure performance, the load should be tested over a chronograph.

In order to comply with industry standards, Hornady publishes data for ammunition derived from testing with Sporting Arms and Ammunition Manufacturers Institute (SAAMI) specification test barrels. SAAMI specifies minimum and maximum chamber sizes and certain barrel lengths for certain cartridges. For instance, most rifle test barrels are... Continue Reading

Ballistics information for each bullet and cartridge is available on our online store. You'll see a tab called "Ballistics" at the top of each specific product page.
