The following are the steps that one has to adhere while working on a dual reloading press. Note that they are significantly different as compared to when working on a single reloading press.
Step 1: Clean and Check
The first step that all individuals should follow when reloading press is ensuring that it is clean and thoroughly checked. You should use a soft cloth to wipe all the dirt while at the same time ensuring that the dust does not scratch the case and the sizing die. After cleaning, check all the safety issues and ensure that there will be safe reloading. Some of the safety issues that you can detect include excessive bulges and case head separations.
Step 2: Lubricate the Cases
Lubricate all the cases before you can insert them in the sizing die is necessary due to the force involved. Spread lube around the pad so that it can lubricate the case with ease. Do not grease the shoulder of the case to prevent dents. You can consider using carbide sizer die for reloading activities because it will help you to bypass the lubricating process. The carbide sizer die is smooth and cannot get stuck while reloading.
Step 3: Install the Shell Holder
After lubricating, you should install the shell holder into the press ram by use of small but twisting motion. Using a simple, slow, and twisting motion will ensure that the shell holder perfectly fits and grips the head of the cartridge. However, ensure you have the best shell holder in the industry as a significant number of shells used crack easily, especially when they are being installed. It’s important to be cautious so that you can minimize damages.
Step 4: Install the Sizer Die
This step involves installing the sizer die so that it touches the shell holder. It is your role to ensure that you press the sizer die until it goes down to the point of touching the shell holder. After turning the sizer die to about one-eighth or one-quarter turn, you can now use the large rung rock so that you can secure the sizer die in a single place. Individuals using the carbide sizer die are encouraged to leave sufficient between the shell holder and the sizer die.
Step 5: Size the Case
After sliding a case into the shell holder, you can go ahead and run the case into the sizer die. It should be a gradual and gentle process that does not involve much work but high levels of sensitivity. Make sure you are running the size holder to the shell when you have already lowered the press handle. The process is done gently and with much care so that it can size the case into the most preferred dimension.
Step 6: Check Length and Trim where Necessary
As you have noticed, cases are likely to stretch after several rounds of firing. This stretching causes them to be longer than the maximum or the required length. In case the cases are longer than the maximum specified length, there is a probability that there will be safety issues and chambering will not be as recommended. You should consider checking a reloading manual so that you can get the required case length.
Step 7: Chamfer and Deburr
Chamfering and deburring is a simple strategy that individuals forget when they are using a dual reloading press. As you have noticed in the previous step, the length of the case has been trimmed, if at all they were longer than the expected length. This step helps in removing all the burrs that were left on the mouth of the case after trimming. This process allows a bullet to seat on the case quickly. You will quickly get deburring tools without much work.
Step 8: Measure and Set the Powder
This is the second last step but one of the most important one. At this stage, you will be required to consult the manual so that you can determine what type and the specific amount that is needed to reload your cartridge. Using a weighing scale, you will measure the required amount and weight of the powder and load on the round. You should make sure that you use the recommended scale for safety reasons.
Step 9: Bullet Seating
This is the last step of reloading a dual press where you are supposed to lower the press handle with one hand and insert the bullet through the mouth handle. You should ensure that the bullet is seated deeper by lowering or turning the seater plug down.
