Another must-have is a reloading manual, which will give you the details on how to reload the ammunition you're making. Making ammunition is following a recipe. The basic idea is X grains of Y powder with a Z-grain bullet will yield such-and-such velocity at a particular pressure out of a particular barrel length of gun. Now, the recipe and the yield depends on the reloading manual that you consult with. For instance, a recipe for standard .45 ACP hardball might read something like this: .45 ACP 230 gr FMJ bullet seated on either, say, 4.6 grains of Alliant Bullseye or 5.6 grains of Winchester 231 will get you 830 feet per second out of a Government (5-inch barrel) 1911 and produce around 20,000 psi. Make sure to carefully note all details of a reloading recipe. Guns have pressure tolerances, and exceeding them can have disastrous consequences. Handloading is very popular among the magnum revolver crowd, but some magnums are just built as tough as others. (We won't say who, but it's rumored that "Schmaurus" and "Pith and Schmesson" revolvers should not get regular diets of hot handloads.) That said, the phrase "Ruger handloads" exists for a reason. Again, the recipe is going to depend on which reloading manual you get, but you get the general idea..
