The Lyman Black Powder Handbook 2nd Edition is entirely new, from front to back. Data development was over three years in the making and includes all the popular black powder and cowboy action cartridges, as well as 10, 12, and 20 gauge shotshells. Unique down range velocities and energies are shown for each pressure tested load. Powders such as Goex, Elephant, and Pyrodex are all present, along with round ball, conical and sabot projectiles. With the help of muzzleloader expert Sam Fadala, Lyman's goal was to produce the most comprehensive black powder manual available. The book covers subjects such as choosing a muzzleloader, ignition, propellants, maintenance, building the best loads, and more. Mike Venturino provides coverage of all the black powder cartridges as well. A must-have for all black powder shooters.
