Home Forums Reloading Reloading Software Case trimmer

Looking to buy a new power case trimmer, any ideas as the best one and why?

The Giraud Power Case Trimmer is a beast when it comes to speed and precision. It's like lightning-fast trimming with surgical accuracy. Plus, it's built tough, so it can handle your reloading adventures like a champ.

Who handles them?

Girauds are very nice but I prefer the Henderson.

Trim pro with 3 way cutter powered by Dewalt. Quick and easy. 👍

LE Wilson. https://lewilson.com/

It is HARD 2 beat the Wilson most other trimmers measure off of the case rim which is not always concentric
The 1 I like is the Worlds Greatest Trimmer as it measures from the shoulder

I use the RCBS Trim Pro motorized, with 3 way cutters and a micrometer dial. It measures off the flat cartridge base, like in the "trim to length". If you have a CH trimmer, as I also do, with chamber type case holders, you can flip the case first then square the base of new brass, and then you trim to length, uniform the pockets, debur the flash hole, fire form and for match brass, segregate by H2o capacity. If I see real uneven neck thickness, I outside turn the necks only to uniform the necks, leaving a hair of unturned brass the full neck length. It is a one time prep, except the trim when or if the brass grows.

One thing I wish I had considered when I started acquiring nicer reloading equipment was the expense of caliber-specific and cartridge-specific accessories for case trimming. The nicer stuff is expensive either way, but costs can get out of hand if you keep buying and swapping for guns chambered in new or different cartridges.

I went with a couple of the UGLY SRT TRIMMER with the collets I required...so I could set one up for each rifle I am currently using.

To the right side of drawer, with spares in middle. Uses a cordless drill as a power source.

I have a couple Wilson's. I started using a Lee Quick Trim and now have a turret press set up with four dies so I don't have to do a bunch of adjusting.

I think you'll find there really isn't one so much better than another that we can call one the best. Each one will trim a case to normally the spec's. you want if you used it right. I've used this one, a very old R.C.B.S, a very old Lyman and one other I don't recall the name of. They all did what they were supposed to do, IF, I did my part right! So, do you simply want to spend money on a power trimmer thinking you got the best or could you be happy turning a crank handle? Either way you'll get the right length if you do your part right. Reason for so many people using old manual trimmer's. My reason is I'm cheap and don't want to spend more money just to do the same job maybe faster!

Lot of people go to the auto trimmer and generally auto other tools at the same time as they want higher production. Well if that it for you, go for the auto trimmer, probably work well which every one you get.

A Giraud trimmer was one of the best investments in saving time at the reloading bench. Being able to trim, chamfer and debur in one pass was a time saver.

I’m still relatively new to reloading but my kit I originally purchased came with a Lee Quick trim kit. I’ve purchased the quick trim dies and it does work very easily and is simple to use. The quick trim kit uses the press for trimming.

I have a standard Lyman power trimmer but it collects dust now because I have the Lyman Brass Smith trimmer. The Brass Smith does not work on straight walled cases.
