Giraud Case Trimmer

The Giraud Case Trimmer rocks!

Giraud tool

In the past trimming cases has been my most time consuming and tedious case preparation task. Using my new Giraud Case Trimmer I can routinely trim over 100 cases in less than 15 minutes without rushing the work. It works out to about six to eight seconds per case. The unit arrived very quickly and was completey set up for .308 Winchester cases. All I had to do was find some sized cases, plug in the trimmer and throw the switch.

You feed the case into the spring loaded case holder and down onto the cutter, the cutter trims and champhers the inside and outside of the case mouth. Remove the case and do the next case. A small amount of lateral torque helps seat the case firmly in the shell holder and reduces chatter. Chatter is only a problem on previously untrimmed cases. The unit is mounted in a bracket with rubber feet on two sides that allow you to orient the unit for horizontal or vertical feed. I chose vertical so I wouldn't slide the unit when pressing a case into the cutter.

Cleanup consists of placing the unit upside down over a trash can, Sliding the the plastic chip guard off the spindle housing and letting the chips fall into the trash.

Using my olde Forster; trimming 100 cases would have taken close to an hour plus another 20 minutes to champher the case mouths. More time for cleanup because the Forster throws chips everywhere when you turn it with a drill motor.

The Giraud trimmer does make a fair amount of noise but no more than the drill motor I use to turn the Forster. Not a problem if you're watching a game on the tube where you don't really need to listen to the audio portion.

After using the case trimmer for around 600 cases I noticed quite a bit of chatter while trimming the cases. I later discovered that much of the chatter was caused by the shell holder coming loose. Unfortunately I did not discover this until after I had trimmed ~300 sized cases about .015" too short. The first 600 cases were trimmed perfectly so I had little reason to suspect that the shell holder that sets the length was going to move. Because of the large volume of cases you can trim with this unit check your trim length often in a case gauge or with calipers. I check at least three cases out of every 50. I added a bit of blue loctite to the shell holder locknut to reduce the chances of it coming loose again. Since doing this I have trimmed over six hundred cases and there is no sign of it coming loose. The shell holder is threaded with the standard 7/8-14 thread so any lock nut can be used. I am a bit wary of using a split steel lock nut because I do not want to distort the shell holder but the RCBS style with a brass set screw may work just fine.

At US$330.00 plus shipping it is expensive but well worth the investment for anyone who has a lot of brass to trim. You need a shell holder for each cartridge but they're not very expensive.

Aloha DJL4570:

Excellent post! I have been using a manual RCBS trimmer and it has been painfully slow. Even with the new cutter that also chamfers the inside and outside at the same time takes a long time to do 100 cases.

Thank you for the heads up! Where did you buy the unit from?

Aloha,

Tom O.

I agree with you. The Giraud Case Trimmer is great.
I was doing my cases by hand, but once I got to doing 900 cases at a time, It took forever and got lots of blisters.
It is not inexpensive but does the job extremely well.
Since it trims and chamfers the cases at the same time, it saves a lot of time.

It is a quality product. If you do any amount case trimming, this machine is great.

I should have logged in before posting the note above. In the mere week that I have used the trimmer my pile of sized and trimmed cases has grown from a scant 600 sized awaiting trimming to over 1800 sized and trimmed cases (not counting the ones I tossed after trimming them too short). 36 J&J storage boxes of 50 cases with a few odd extras tossed in on top. Now I have to swage them, uniform the pockets and deburr the flash holes.

Hmmm, I need to order more Hornady case lube. At this rate I'll run out fast.
