Frequently Asked Questions

What is the RCBS Trim Pro 3-Way Cutter and what does it do?

The RCBS Trim Pro 3-Way Cutter is an accessory for RCBS case trimmers that performs three operations simultaneously: trimming the case length, chamfering the inside of the case mouth, and deburring the outside of the case mouth. This streamlines the brass preparation process for reloading.

How do you adjust the inside chamfer depth on the RCBS Trim Pro 3-Way Cutter?

The inside chamfer depth is adjusted via a set screw located on the bottom of the cutter assembly. Loosening the pilot's lock nut allows you to screw this set screw in or out, which raises or lowers the pilot, thereby controlling the depth of the inside chamfer cut.

What causes the RCBS Trim Pro 3-Way Cutter to bind, and how can it be fixed?

Binding typically occurs when the cutter head and the pilot are not properly aligned. This can happen during installation or adjustment. To fix it, ensure the cutter head is slightly offset from the pilot, allowing them to move independently. If binding occurs, carefully try to free the assembly, but be aware that damage to the pilot is possible.

Is the RCBS Trim Pro 3-Way Cutter caliber specific?

Yes, the RCBS Trim Pro 3-Way Cutter is caliber specific. You need a cutter designed for a particular caliber, or you can use caliber-specific pilots with the cutter body. The video shows examples for both 30 caliber and 22 caliber brass.

What are the benefits of using the RCBS Trim Pro 3-Way Cutter?

The primary benefit is efficiency, as it combines trimming, chamfering, and deburring into a single step. This saves time during brass preparation for reloading and can produce very clean case mouths, reducing the need for separate deburring and chamfering tools.
