Beginning the reloading process, the first step, after assembling your tools at a suitable workplace, and solid base for your loading tools such as a short piece of 2”X 6” is important to decap the fired brass.
This is accomplished by simply placing the fired brass case into the decapping die, and using the punch with the small diameter needle-like end, inserting this end into the brass case, through the flash-hole and then rapping lightly with a non-marring hammer on the decapping rod, thus popping the spent primer out of the case. By necessity, the primer must be removed from underneath the decapping base to allow a space for the primer from the next fired case when it too is decapped.
Once the fired brass cases are decapped, it becomes necessary to clean them prior to resizing. Cleaning the cases prevents surface grime, powder residue and other abrasive agents from scratching the interior surface of the reloading die. While this seems a trivial step, the purpose is not necessarily to enhance cosmetic appearances of the brass, but to protect the machined surfaces of the resizing die chamber. Simply use some #000 steel wool. It only takes a few seconds with a twisting motion to clean the brass of outer grime and residue.

Cleaning the now-empty primer pockets is best done at this stage of the operation as well. This is where one of those “optional accessory items” listed in the list of tools and expenses really pays off! Cleaning carbon residue from the primer pockets insures uniform primer seating depth, and also mandates a visual inspection of the pocket and at a glance note the flash-hole is clear of any obstructions.
With both the exterior of the brass and the primer pockets clean, lubing the exterior surfaces of the case is necessary to prevent sticking in the resizing die.
Once the lube is applied to the deprimed and cleaned cases, they may be resized. The case is inserted into the die.
Using a non-marring hammer, drive the case fully into the sizing die, so that the rim of the case is flush with the bottom of the sizing die. Some cartridges/calibers require much more force than others to accomplish this task.
The next step does two functions. First a new primer is seated into the clean primer pocket, and concurrently the case is partially extracted from the resizing die. Before conducting this phase of the operation, it is necessary to consult the reloading data to be used, to determine the correct primer for the selected load. Don’t be mislead, all primers are NOT the same. Many loads are very primer specific. Be sure, and not sorry.
Center a new primer, anvil-up in the priming base (the base with the bullet seating stem coming off the side and a spring loaded base in the center). Then, center the resizing die (containing the resized brass case) over the primer on the priming base. Then, using the long, blunt ended priming rod, drive the brass out of the sizing die chamber and onto the primer under it. After just a few rounds a “feel” for this process is attained, and the procedure goes quickly and smoothly once a routine is established.

Once the case is successfully primed, remove the sizing die from the priming base, and the case will protrude somewhat out of the die
Center the sizing die over the decapping base, and using the blunt-end priming rod and a sharp rap from a non-marring hammer, eject the now resized and primed brass case from the sizing die body.
Leaving the brass case in the decapping body, use the expanding/flaring plug to expand and slightly flare the case mouth to accept a bullet. Actually very little force is necessary for this step, and light taps of the hammer are all that is needed. Excessive force here will only ruin cases by collapsing them. Don’t overdo a good thing!
Depending upon the cartridge, the number times the brass has been loaded, and the pressure intensity of those loads, the case may, and will stretch in length. This can cause a hazardous condition, and requires trimming brass to a uniform length both for uniformity of the loads, and safety as well. For this purpose the Lee Case Trimmer is included in the list of recommended equipment at the beginning of this article. The Lee tool greatly simplifies the process, and insures that each and every case is trimmed to a specific uniform length without necessitating the procurement of a costly dial caliper to measure brass. Usually brass only needs trimming every third to fifth reloading, depending upon the cartridge and pressures it generates.
Due to the design nature of the Lee Case Trimmer, it must be used before the case is primed. When using the Lee Loader kit, it might be necessary to size the brass, and totally eject it from the sizing die, trim the brass and chamfer it, then prime the brass case in a separate operation, using only the priming base for this purpose.
The Lee Case Trimmer is a four-part tool which gives great flexibility by enabling the user to change caliber/cartridge application with only about a three-dollar investment.
Once the case trimmer is assembled, case trimming is simplicity defined!

Should trimming of cases be necessitated, chamfering the case mouth is also necessary. This step removes any burrs remaining after the case trimmer peels away excessive case-neck length. Too, it puts a slight inside bevel on the brass to facilitate bullet seating.
Now, all our cases are cleaned, resized, trimmed, deburred, primed, expanded and flared, ready for the main event: loading with powder and projectile!
Included with every Lee Loader is a chart of caliber/cartridge specific loading data. This data correlates with the included volumetric powder measure included with the kit, and various combinations of bullets and powder, utilizing that volumetric measure for safe and effective powder charges when combined with the listed bullets.
The simple addition of at least one and preferably two handloading manuals gives a checks-and-balances aspect to your load selection. Too, more loading data is presented which, when combined with the Improved Lee Powder Measure Kit, will open greater variety of loading options to the handloader. Included with the Powder Measure Kit is a powder charge-weight slide-rule, that calibrates a given desired charge weight of selected powder into a volumetric value measured in cubic centimeters. The plastic measures in the Powder Measure Kit are also calibrated in cubic centimeters and thus selecting a desired powder charge is quite simple, match the volume of the measure to the necessary volume of powder to attain the target charge weight.

The Modern Reloading Second Edition manual by Richard Lee found listed in the chart at the beginning of this article, has a vast array of loading data, directly from the powder manufacturers, and organized by Lee into a format that centers around the use of the Lee Improved Powder Measure kit, and has most of the data listed not only in grains of powder by weight, but in volumetric measure in cubic centimeters to directly correlate with the values printed on their powder measures. By using this data, it is a simple matter for the budget-minded handloader to maximize the potential variety afforded by this effective system. Too this manual gives some excellent loading advice, instruction and cautionary information applicable to the novice and experienced handloader alike. It is a well worth-while addition to the handloading resources, especially to the user of the Lee Loader.
With the cases carefully prepared, bullet and powder selections determined, and careful double checking of powder charge weight and corresponding powder measure verified, everything is ready for the actual loading process.
Here is where the Improved Lee Powder Measure Kit. Note the various cc values listed with each measure comes in handy. This simple kit expands the horizons of the basic Lee Loader in allowing a virtually unlimited selection of powders and bullet weight combinations for any given cartridge.

Be sure to only have one powder measure out on the reloading bench at a time, and only one type of powder as well. Following this practice will safeguard against a possible mistake in powder charge weights due to a mix-up in powder measures, or a switch in powder types. Either of these errors can, and will mean the difference between a well balanced load that performs to expectations, and a disaster. Be safe, keep only one of each on the bench at any given time. Use of a small metal container for the powder that will hold about a quarter pound.
Be careful of what container is selected, as some plastics generate considerable static electricity, and may possibly cause combustion of the powder contained therein from the static electricity! Play it safe and use a metal container.
This brings the discussion to powder dispensing technique. Yes, as mentioned above, dipping is the correct term. The powder measure, or dipper, is pushed straight down into the powder, base first, until gunpowder flows over the edges or rim of the dipper and fills the cavity with powder. Then, once the measure is full it is lifted straight out of the powder container, and leveled off with the edge of a business card with a smooth, fluid sweeping motion. Even veteran handloaders might be surprised at the consistency of dipped powder charges. Using a repeatable consistent technique results in startlingly uniform charges of powder when using nothing more than volumetric powder measures. However, this uniformity is entirely dependent upon proper technique. NEVER, NEVER USE A POWDER DIPPER AS A SCOOP! Scooping these dippers through the powder causes wide variances in powder charge weights.

In loading the prepared brass, the case must be placed upright in the decapping base, and the resizing die sitting on top of the base, the brass case resting inside the die. Then, carefully pour the properly leveled powder charge into the top of the loading die.
After dropping the powder charge into the case, then drop the appropriate bullet base-first into the top of the loading die as well. Then, using the concave end of the bullet seater/priming base unit, seat the bullet into the prepared and powder charged case with light taps from a non-marring hammer. In adjusting the seating stem for the proper seating depth, it is important to incrementally check the seating depth of the bullet into the case.
Once the bullet is seated to the proper depth in the case, adjust the seating stem lock-ring on the seating stem, jamming it up against the priming base, until it firmly locks the seating stem depth into place. From here on out, each and every bullet will be seated to the exact same depth without having to check each and every bullet as it is seated.
With the bullet properly seated in the case, a roll-type crimp is applied using the opposite end of the resizing die. A few light taps with a hammer creates a nice tight roll crimp on the cartridge mouth into the bullet crimp groove.
Removing the die from the newly loaded round of ammunition reveals a nearly perfect roll-type crimp on this round.
