Hornady V-MAX^® bullets consistently achieve accuracy and rapid fragmentation at all practical varmint shooting velocities. Each cartridge is loaded to ensure optimal pressure, velocity, accuracy and lot-to-lot consistency. Hornady produces most of the brass for our Varmint Express^® ammunition. Brass is chosen to ensure it meets our high standards for reliable feeding, corrosion resistance, proper hardness, and the ability to withstand maximum chamber pressures. Like the powder, each primer is carefully matched to individual loads, and all are chosen for their ability to quickly, completely and reliably ignite the powder charge.
