Some never move past the basics and enjoy the hobby for a lifetime, just for the savings alone. For others though, reloading becomes the gateway to precision that no factory ammunition can provide, where groups are measured in thousandths of an inch and accuracy is king.

4 Handloading can resurrect a family heirloom that uses ammunition long since discontinued or turn an obscure war prize into a shooter. A good handloader can transform a deer rifle into a varmint rifle or a low-recoil plinker. In the end, it is this versatility, along with savings and accuracy, that keep handloaders happily loading cartridges. SETTING UP nThis article is intended as an overview of reloading basics. It needs to be supple-mented by other reloading manuals, including at least one by a prominent bullet manufacturer.

5 Barnes, Sierra, Hornady and Nosler, along with many others, all offer Considerations and Helpful TipsGetting Started:BY ROB BEHR3 EDITION books on the subject. Friends and the Internet are also useful resources for loading tips, but they need to be treated with a grain of salt. If their advice differs significantly from published data, common sense should favor companies with ballistic labs and staff RELOADING PLACE nA good reloading space should be free of distractions, well lit, dry and warm enough to be comfortable. Ideally it should be a room dedicated to the hobby.

6 The bench simply needs to be sturdy. A press exerts quite a lot of force on the bench, which must be stable enough not to break or bounce as it is used. Several nice reloading benches are available complete from their manufacturers. Plans for dedicated re-loading benches are also readily available from Internet sources. Even a reinforced kitchen Table works well. The bottom line is that handloaders need a bench before the first round can be BARE ESSENTIALS nThere are basic tools every handloader needs, and reloading kits offer an excellent way to get started.

7 Kits should include most of the items listed below. The rest will need to be purchased separately. Whether they come from a kit or individually, these are the tools everyone needs to safely begin reloading:SINGLE-STAGE PRESS This is the main tool used for handloading. It uses mechanical advantage to resize fired cases and seat bullets. Most have some provision to seat DIESA rifle die set is usually comprised of two dies. The first sizes and deprimes fired cases, and the other seats a new bullet. For straight-walled cases, like many pistol cartridges, die sets will include a third die used to flare the case mouth prior to bullet mate a case into the press.

8 They are machined to match the rim or extraction groove of the cartridge being MEASUREMost kits will contain a Powder scale, most of which use weights on a balance beam to measure Powder . More expensive options may include an electronic scale, which can be more Accurate and TRICKLER A tool used to precisely pour (trickle) Powder onto the TRAY AND LUBE Lube is used to keep resized cases from sticking in the die. The lube tray is a simple roll-on type applicator. It s easy to see that reloading makes good economic sense. 4 EDITION FUNNEL A funnel specifically designed to pour Powder into a case TOOL A tool used to chamfer and deburr the case CALIPER Precise measurements are required for safe and reliable handloads.

9 A good caliper is the best tool for the TOOLMost presses come with a tool to safely prime cases. Several after-market hand tools are also available. CASE TRIMMERC ases stretch during firing and loading. This may eventually cause problems with cham-bering and higher than expected pressures. Lee offers trimmers intended for individual calibers. Lathe-type trimmers add versatility for the larger scale handloader. THE CHAMBER, THE THROAT AND NECK SIZING nFor a handloader, understanding a bullet s interaction within the chamber is funda- mental to good accuracy and safe handloading. The throat is a smooth, funnel- like area of the chamber that guides a bullet into the rifling.

10 This space allows a bullet to move forward relatively unimpeded for several thousandths of an inch before it begins to swage down to the bore diameter and into the rifling. Precise align-ment of the bullet with the throat is a key to rifle accuracy. If a bullet is misaligned with the throat, pressure will still drive it into the barrel, but on a plane other than its ideal ballistic axis. A bullet on its ballistic axis spins much like a well-thrown football. Off its axis, the bullet will yaw, severely diminishing accuracy. This is most commonly seen when a bullet (usually light and short for the caliber) is seated far away from the throat.
