This 142-grain hollow point boat tail bullet is designed for precision target shooting and performs best with a fast twist rate of 1:8" or faster. Commonly used powders include H4350, Varget, and Reloder 16, with typical velocity ranges between 2600 and 2750 fps depending on the cartridge and barrel length. For safety, loads should always be developed by starting below maximum published charges and working up gradually while monitoring for pressure signs.
