We know many of you guys have a Forster case trimmer (hand lathe) sitting on your reloading bench. This tool does a good job of trimming cases to length. But did you know that an inexpensive accessory will allow your Forster case trimmer to chamfer while it cuts? Here’s the skinny on the 3-way head for the Forster case trimmer.
Tool Cuts Brass to Length, and Chamfers Inside and Outside
Forster’s 3-in-1 Carbide Case Mouth Cutter works with all existing Forster case trimmers. This unit does three jobs at the same time. It trims the case to length, it puts a 14-degree chamfer on the INSIDE of the neck, AND (last but not least), it cuts a 30-degree chamfer on the OUTSIDE of the neck. It does this all quickly and efficiently — in a matter of a few seconds. We tested the new tool ourselves on a few cases. The tool is solid and well made. The carbide cutting tips do perform a very clean cut. Be aware, however, if you have turned your necks already, you may have to reset the blade positions before you start trimming your brass.
Forster’s CFO, Robert Ruch, demonstrates the 3-in-1 case trimming/chamfering tool in the video above. As you can see, the tool turns very smoothly (no chatter). The actual cutting time, per case, is just a few seconds. The tool has an MSRP of $88.00, but it sells for around $65.00 to $70.00 at major vendors. Forster’s 3-in-1 Carbide cutting tool works with all existing Forster case trimmers and other hand lathes with a .490″ shaft diameter. The unit fits over the cutter shaft and secures with one set screw. The 3-in-1 cutter is available for five (5) calibers: .224, .243 (6mm), .264 (6.5mm), .284 (7mm), and .308.

How do you trim your cases? We use a variety of tools, including power case trimmers. But our go-to trimmer for Benchrest-type cartridges is the L.E. Wilson Trimmer unit, now available in a handsome and durable stainless assembly. This thing is slick. It trims very precisely with the use of Wilson case holders combined with a micrometer-type stop for length control. As sold complete with micrometer, quick clamp, and metal stand, this new Wilson Stainless Trimmer is $139.95 at Creedmoor Sports. We think that’s a fair price for a unit that can last a lifetime, trimming many thousands of cases.
In this video, Bill Gravatt demonstrates the new Stainless Wilson trimmer. Gravatt offers some smart tips so this video is worth watching even if you’ve used a Wilson trimmer before:
Tips for Trimming with Wilson SS Micrometer Trimmer:
1. After inserting brass in the case holder, tap the case lightly to ensure it seats fully.
2. When starting your case-trimming session, do one or two test cases to check cut length. Adjust length with micrometer, then test length again. If “good to go”, set length stop. NOTE: Release the Stop Screw to make major adjustments. Use the Micrometer to make fine adjustments, in .001″ increments.
3. After trimming operations, be sure to chamfer case mouth after cutting to remove burrs. NOTE: After you have made the chamfer, we recommend gently spinning the chamfer tool backwards a couple times in the case neck. This will burnish/smooth the newly-cut champing, which helps with bullet seating.
Features of Deluxe Wilson Stainless Case Trimmer with Micrometer
— Long lasting Stainless finish with Micrometer adjustment.
— New 304 Stainless Steel Handle included with Micrometer Trimmer.
— Rotary-style clamp swings to secure case-holder — quick and easy.
— Larger stop screw adjustment from 3/8″ (old) to 1/2″ (new) with increased width on stop nut. Coated with black oxide for a long lasting durable finish.
— Made in the USA with American Steel.
— Power Adaptor compatible.

Trimming and chamfering brass are tasks hand-loaders grow to hate. Those chores are time-consuming and tiresome. Thankfully there are faster, better alternatives to manual trimming/chamfering. In this article, Forum member Erik Cortina shows how to use the Giraud tool which trims and chamfers in one operation. Erik has his own YouTube Channel dedicated to precision reloading and accurizing. Here we feature Erik’s video about the “mother of all brass trimmers”, the Giraud powered case trimmer. Erik says: “If you do volume reloading… this is the only trimmer to get. It not only trims to length but it also chamfers your case mouth inside and out.” In his video, Erik offers some very clever and useful tips that will help you get the most from your Giraud.
This is a manufacturer’s photo showing an older model.
The Giraud trimmer is very precise. When set up correctly, it can trim brass with amazing consistency. In the video, Erik trims five pieces of brass in 15 seconds (6:32 mark). He then measures all five with precision calipers (7:00-8:08). All lengths are exact within .0005 (half a thousandth). Erik notes that the Giraud trimmer indexes off the case shoulder. As long as you have fire-formed brass with consistent base-to-shoulder dimensions, you should get very consistent trim lengths.
The secret to the system is a 3-way cutting head. This cutter can be swapped in and out in a couple minutes with wrenches provided with the kit. Erik has three different heads; one each for 6.5mm, 7mm, and .30 caliber. The video shows how to adjust the cutting heads to match caliber diameter (and to get the desired amount of inside/outside chamfer).
To trim and chamfer cases, you simply insert them nose-first into the cartridge-specific case-holder. Erik offers a smart tip — He uses a die locking ring to position the cartridge holder (3:15). This can be locked in place. Erik says die locking rings work much better than the hex-nuts provided by Giraud (with the hex-nut, one must re-set cut length each time you change case-holders.)
The Giraud can be used in either horizontal or vertical modes. Erik prefers to have the trimmer aligned vertically, allowing him to push cases down on the trimmer head. But the trimming unit has twin sets of rubber feet, allowing horizontal or vertical orientation.
Improved Case-Holder Made with Chamber Reamer:
For his .284 Shehane, Erik had to create his own case-holder (Giraud does not make one for that wildcat cartridge). Erik used his chamber reamer. To his surprise, Erik found that the brass was easier to trim in the custom case holder (compared to the Giraud-made spring-loaded holders). With a perfect fit, trimming and case extraction went more smoothly and the process was easier on his hands. (See 9:00-10:00). Based on Erik’s experience, you may want to create your own custom case-holder.
Trim Bullet Meplats Also
With a special bullet-holder fitting and meplat cutter head, the Giraud power trimmer can be used to trim bullet meplats. Trimming meplats can help make the Ballistic Coefficents of a batch of bullets more consistent. Uniforming meplats is also often done as a first step in the process of “tipping” bullets to improve BC.

We are organizing our crew for the 2013 SHOT Show, which runs January 15-18 in Las Vegas, at the Sands Expo Center.

Hornady recently introduced its new multi-function case prep center. (We call it the “Tower of Power”). This machine trims cases to length, chamfers the case mouth (inside and out), and cleans the inside of necks and primer pockets. On the top part of the case prep center you fit your case in a shell-holder then lower it down on a powered cutter. It’s sort of like a drill-press, except the cutter turns rather than the brass. On the bottom of the prep center are six (6) horizontal power take-offs. These can be fitted with inside and outside chamferers, a neck brush, and primer pocket brushes.
The new Hornady Case Prep Center, product No. 050012, is available at vendors now. MSRP is $431.67, with expected “street price” around $300.00. You should definitely watch the Video linked below, as it shows the case trimmer in action. If our written description of the inline vertical trimmer left you confused, it will quickly become clear once you watch the video.
NOTE: You can see tool details better on YouTube.com, which will display the widescreen version of the video taken at SHOT Show. You can also select “high quality” playback on YouTube.com.
