\"howCase trimming is one of the most profitable and beneficial approaches for shooters around the glove.<\/p>

If you have occupied huge time reloading cartridges, then you must know the importance of a brass case trimmer<\/a>.<\/p>

When you fire a round, the brass case slightly increases in length from the pressure of firing.<\/p>

Over the phase of time, the case will extend and need to be trimmed. The trimming is required more often in high-pressure rounds of fire.<\/p>

As a result, the brass cases stretch out at an extent that it becomes impossible to reload. Trimming plays a vital role in such a situation.<\/p>

How to Use Case Trimmer
<\/strong><\/h2>

You will be surprised to know that without the right tools and proper method, all your trimming effort may go in vain. So I am here to guide you through the whole process of trimming.<\/p>

1. Assemble Pilot and Collets in Case Trimmer<\/h3>

Select the correct pilot and collet for trimming the case. Insert the pilot into the cutter shaft and collet into the collet Screw.<\/p>

2. Insert Case and Adjust for Length<\/h3>

Now, you will have to insert the case and follow the steps mentioned below;<\/p>

  • With tension on the collet released, insert the base of the case that is going to be trimmed, into the collet.<\/li>
  • Move the Pilot into the neck of the case. With one hand on the Crank Handle, push the base of the case against the bottom of the collet.<\/li>
  • Ensure the base of the case is held firmly against the bottom of the collet and the pilot is supporting the inside case neck, then tighten the collet.<\/li>
  • Ensure the cutter teeth are in contact with the case neck, then tighten the stop collar coarse adjustment-lock screw.<\/li><\/ul>

    3. Make Trial Cut to Check Case Length<\/h3>

    To ensure the case length is accurate, you have to make trial cuts to check and confirm the measurements.<\/p>

    • Turn the crank handle to make a trial cut.<\/li>
    • Remove the case and use a caliper to check its length.<\/li>
    • Consult a reliable manual for correct case length.<\/li><\/ul>

      4. Make Fine Adjustments for Case Length and Set Stop Collar<\/h3>

      To set the stop collar, proper adjustments for the case length is required. Herein, you have to follow the steps below;<\/p>

      • Turn the Stop Collar Fine Adjustment Screw (one complete turn equals .032″) in case length:<\/li>
      • A clockwise turn increases case length.<\/li>
      • An Anti-clockwise turn decreases case length.<\/li>
      • Once the Case Trimmer is fine-adjusted for case length, lock the Stop Collar Fine Adjustment Screw in place using the Stop Collar Fine Adjustment Lock Screw.<\/strong><\/li>
      • Make a final trial cut and check case length. Re-adjust, if necessary.<\/li><\/ul>

        5. Trim Batch of Cases<\/h3>

        Now that everything is checked and confirmed, it\u2019s time to start trimming your cases. However, be mindful of the following;<\/p>

        • The Case Trimmer is now set up to trim a batch of cases to the exact same length.<\/li>
        • Occasionally lubricate the Cutter Shaft to Bearing surface with a drop of light oil when trimming.<\/li>
        • Label and save a master setup case that is trimmed to the correct length for each caliber. This will save setup time in future trimming operations.<\/li><\/ul>
