RCBS Trim Pro High Capacity Case Trimmer Collets Review

Let’s Dive into RCBS Trim Pro High Capacity Case Trimmer Collets

Case trimming is an often overlooked, but absolutely critical step in reloading for consistent accuracy and safe ammunition. RCBS, a name synonymous with quality reloading equipment, offers the RCBS Trim Pro High Capacity Case Trimmer Collets to facilitate precise trimming of larger caliber cases. These collets are specifically designed for use with the RCBS High Capacity Trimmer, expanding its versatility to handle magnum and large-bore cartridges.

I needed a reliable solution for trimming some .45-70 Government cases I was prepping for a vintage rifle. My old universal chuck trimmer just wasn’t cutting it (pun intended!) with those larger, straight-walled cases. These RCBS collets promised a secure and accurate fit, something my existing setup sorely lacked.

The collets arrived in a simple, no-frills package. They are machined steel, with a silver finish. My initial impression was one of solid, functional design.

I considered universal collets from other manufacturers. But I decided to stick with RCBS due to their reputation for quality and the fact that these collets were specifically designed for the Trim Pro High Capacity Trimmer I already owned. It felt like the safest bet for achieving consistent results.

I was cautiously optimistic. I’ve had mixed experiences with aftermarket reloading accessories. But given RCBS’s reputation, I hoped these collets would live up to the expectations.

Real-World Testing: Putting RCBS Trim Pro High Capacity Case Trimmer Collets to the Test

First Use Experience

I first tested the RCBS Trim Pro High Capacity Case Trimmer Collets while reloading .45-70 Government rounds for my 1884 Trapdoor Springfield. I worked in my reloading room, ensuring consistent lighting and a controlled environment. I focused on achieving precise case lengths for improved accuracy in my black powder loads.

The collets performed flawlessly, even with some older, slightly tarnished brass. They held the cases securely and allowed for precise trimming. The larger cases were easily supported and did not shift during trimming.

These collets were surprisingly easy to use. The instructions were clear. Setting up the trimmer and inserting the cases into the collets was straightforward.

My initial concerns about potential slippage with the larger cases proved unfounded. The collets gripped the cases tightly and did not damage the brass.

Extended Use & Reliability

After several months of consistent use, the RCBS Trim Pro High Capacity Case Trimmer Collets are holding up remarkably well. There are no signs of significant wear or tear on either collet. The steel construction seems highly durable.

The collets still maintain their tight grip on the cases. There is no noticeable degradation in performance. Routine cleaning with a dry cloth is all that’s been needed to keep them in top condition.

These collets have significantly outperformed my previous universal chuck system. The improved accuracy and consistency in case trimming are immediately noticeable on the range. I have consistently produced more accurate ammo since I’ve added this tool.

These collets are perfect for reloaders who work with large caliber cartridges like .45-70 Government, .338 Lapua, or various Sharps cartridges. They are especially beneficial for those seeking increased accuracy and consistency in their ammunition. They are also a great fit for reloaders already invested in the RCBS Trim Pro High Capacity Trimmer system.

Reloaders who only work with smaller, more common calibers like 9mm or .223 should skip this product. It’s designed specifically for larger, high-capacity cases. Those on a tight budget might find the need to purchase multiple collets for different calibers prohibitive.

A chamfer and deburring tool is a must-have accessory to complement the case trimming process. This ensures smooth case mouths for proper bullet seating. Additionally, a case lube kit is recommended for smoother resizing and forming.
