Features of 17 Hornady Hornet:
– Tight Wall Concentricity
Concentricity helps to ensure proper bullet seating in both the case and the chamber of your firearm. Higher concentricity also aids in a uniform release of the bullet on firing, for optimal velocity and accuracy.
– Uniform Case Wall Thickness
Benchrest shooters have long known that uniform case wall thickness is vital to accuracy. We manufacture to extremely tight tolerances to ensure this critical element is as consistent as possible.
– More Reloads per Case
We treat Hornady brass as the foundation for an accurate cartridge, not a commodity. Because we take greater care in its creation you’ll get more reloads from Hornady brass.
– Consistent Weight and Capacity
Every single Hornady case, regardless of the lot in which it was produced, is virtually identical to other Hornady cases in the same caliber. For you, this means consistent pressures, velocity and accuracy — every time.
Sixty years later, the Hornady Manufacturing Company (Grand Island, Nebraska, US) turned Ackley’s idea into a commercial product with a similar cartridge; the .17 Hornady Hornet uses a 20 grain (1.3 gram) “Superformance” V-max projectile with a published velocity of 3,650fps (1,113 metres/second). 
However, the new standardized ammunition and brass is not built to exactly the same dimensional specifications as the original wildcat or the dimensions listed on this page. Hornady’s standard has a shorter body with less taper and shorter overall case length while the overall loaded length remains that of the original .22 Hornet (in order to fit the standard Hornet magazines).
