I ordered a Henderson Precision Gen 3 Powered Case Trimmer on December 27, 2021. It took a while to get here, what doesn't nowadays, but it arrived on February 25 2022 and I couldn't be more excited. I took a video of it the other day as I was prepping virgin ADG brass for my 6.5 PRC and Ryan (@FURMAN) put it on Instagram Reels and it has garnered over 10.5k views in about 36 hours. So, he asked if I was going to review it. I thought about it quickly and said, I should. It is a great tool and something I wished I had earlier, so why not.

Since opening the box I have only trimmed 200 Lapua cases for my 300 PRC and 100 ADG cases for my 6.5 PRC and am wondering why did I not buy this sooner. Yes, it is pricey. But, I am worth it and my time is valuable and so is yours, so save up! And put it on your list.

I will do a full video review of it later when I have a bit more time in front of it as well as time shooting what it helps produce. Please follow along and ask any question you want. I have cutters for 6.5mm, 7mm, .308, and .338 and I look forward to trying every one.

I bought a Gen2 that I had sent in to have upgraded to the new style cutters. Todd is a great guy and I concur with this. I probably shoot more than most but not as many people on here, and this is probably the last high end tool I would give up. I hated trimming, this makes it way more bearable and knocks out chamfer/debut at the same time

I’ve got a Gen 3 also. It is awesome. Makes quick and repeatable work of your brass.

Yes. 3-processes in one. This is a great time saving feature.

I remember you getting yours and I was jealous although I already had mine ordered.

Just watched Sam Millards review on Hendersons website. All I can say is WOW. I need to stop watching reviews on equipment like this. But then again I do have a birthday coming up. Lol
It would be a good birthday present.

Once you use one, you can't go back. Trimmed 260 cases with it last night in maybe 20 minutes?? I use to dread trimming and often avoided it until I absolutely had to. Now I look forward to it.

I put (150) 30 Sherman Mag cases through the Henderson Trimmer last night and changed the cutting head and stop screw from 6.5 PRC. Save it for some time filming B-roll of the cutting head change and setting the screw stop I have to ask myself, why did I wait so long to buy this. The gen 3 vs the gen 2 would be a good reason why but this machine is a timesaver nevertheless because it makes quick work of trimming, chamfering and reaming brass.

My only complain, which is minute btw and similar to many other's, is the stop screw. It took me 2-4 cases to adjust the trim length perfectly but I have no other complaints and like I said, that is a small one.

I realized something today. Once I have the screw stop set to trim the length I want, I can mark it and use another. The trimmer comes with several plus the bolts and nuts can be found locally so I don’t see this as much of an issue as I thought. I marked the 3 stop screws I have set and used so far so it should be easier to setup next time.

I pulled the cutter and stop screw today and put in the proper two to trim, chamfer and deburr 89 pieces of 6.5x47 Lapua brass in about 10 minutes.

I also ordered the brass bin and shaving containment just to tidy up the workspace and increase the flow.

A couple boxes came in for a new 6.5 PRC barrel so I figured I would trim them and time it. The first 100 I stopped and started for video purposes but the second 100 I turned on the stop watch and went start to finish without stopping. Time is valuable and this trimmer allows me to save a lot of it.

You can see that I have it set up with the brass catcher now as well as the shavings containment. The catcher did improve my time.

Mine arrived in March, almost 8 weeks to the day from when I ordered, which is exactly what the website says to expect. I hand load for three rifles - 6.5 PRC, 6.5 CM and .243 which means I needed two different pilots and two different collets. As mentioned above, once you get the set screw set up the way you like them, it’s really easy to swap them out. And using the trimmer is so fast and easy, and CONSISTENT. Never going back. I shaved a couple thousandths off my PRC brass And ran about 125 pieces through it in a few minutes. It was incredibly clean and consistent. Couldn’t be happier with this trimmer. I actually enjoy trimming brass now.

I've had the Henderson since the v3 came out which replaced a Giraud. It does take a little tweaking to get the right length but, once it's set, a drop of the wicking green loctite on the lock nut and it never moves. I 3d printed a storage block for the cutters and bolts so everything is one place.

The neck ID is important for a tight fit on the mandrel. I usually clean up new brass and had to make some new mandrels that were small enough to fit in the new necks.

I recently received one as a birthday gift. Great piece of engineering, and a must for the high volume shooter. I should have bought one much sooner. Always dreaded the time and monotony of case trimming……No more!

Parshal I’ve done the same thing with the pilots. Chuck them up in a drill and a little 400 grit to get them to size. When I do another I think I will go with Forster pilots. They seem to have a bit more surface area on them.

I set the Henderson Precision trimmer up on an Inline Fabrication quick change stand. It is nice to have the flexibility to remove this, put it on the shelves behind me and breakout something else. The trimmer is cranking it out. 5DA6A76D-7ECE-4332-A472-DA3E409D87D9.jpg6C9A6DAC-C0EC-43A9-B992-97B7F27A459E.jpeg

I just got mine, haven't had the time to set it up yet. I didn't get the motor with the intent of making my own, but I may just end up ordering it. How has it been for repeatability? I shoot 3 BR guns and trim everything every reload with the Wilson at the moment, it takes a lot of time!

Couldnt help it. Had a weak moment. Spent 3.25 hours trimming and prepping 225 pieces of brass.......I ordered the Henderson shortly after. Im gonna have so much more time for activities and ......mowing the lawn now !!!
It is a good investment. You will love it. Time is money and time wasted is money down the drain.

I prepped 3x fired 300 PRC brass on Saturday getting ready for So. Africa. It took only a little bit to change the cutting head from 6.5 to 30 cal and it was equally as easy to change the bolt stop and get it adjusted. Blitzing through 100 pieces in just a few minutes alway makes me wonder why it took me a couple years to buy one.

The trimmed, chamfered and deburred brass looked straight up professional and clean.

To date I have user the Henderson Trimmer for; 300 PRC, 6.5 PRC, 338 Terminator, 6.5x47 Lapua, 7mm Max, and 300 Mega for ~1500x.

Game changer is an understatement. Does anyone adjust the trimmer so it chamfers inside at a lesser angle for VLD bullets? The chamfer heads I used prior had a shallower cut which I thought the Berger’s preferred ? 63535823-4C8C-4098-8C6E-AEA4D6EFD725.jpeg

You would think for the cost of them they would have figured out a micro adjust system for them.

The nylon nut and bolt have actually grown on me. I can set one, mark it and use it the next time. Keep one nut and bolt per cartridge and it is an easy change from one to the next.

My Henderson replaced my Giraud and I haven’t regretted it once, it’s been my favorite overall reloading purchase
Is the Giraud for sale? I think I may go that route.
i sold it awhile back, I wish I had it available for you.

Normally I FL size, dry tumble, trim and debur. BUT…..after tumbling i tried to trim with the Henderson and the pilot to the head won’t fit in the case neck. Anyone else having this issue??? I’d hate to trim and size (reverse) might be cutting off more than I need to. I size .004” on the necks for tension.
@Ladd are u having this issue ?

I had the issue when I was sizing 6cm necks with a bushing to get around .003 neck tension. I took the pilot out of the cutter, chucked in a drill, and used sand paper to bring the size down just a hair.

Nice ! Thats exactly what I ended up doing. Touched it up with some steel wool.

We've been running the full Henderson setup for over two years now here at work with a pull out drawer to drop the freshly trimmed brass into. I sometimes prep 1/2 to a dozen different calibers per day. Can't imagine anything else.

Watched 2 videos on it this morning and will be ordering one this week!I'm done with trying to do it with any repeatability by hand(I have the Wilson manual with the micrometer),did some last night and took forever and depending how much pressure I put on the cranking handle I had variations up to .010" plus,I now have 35 pieces of 3 times fired 338LM brass I may not use because of this(may not matter all that much and could probably load/use them for foulers but since Ladd's OCD rubbed off on me I may just pitch them :D ).Had a really hard time keeping anything close to a consistent trim length,then trying to chamfer the edges is a nightmare with both the RCBS Boss case prep center or the little hand held gizmo(if not for the spinning nylon brush to do inside of the case necks I'd pitch them both out into the street).Where did you guys order the little shield and brass containment option from,I don't see it on the Henderson website?

I ordered it all at the same time. I don’t think he makes the shield and catching trey in house so he has to wait for those parts to arrive. Just ask him. Well worth the money

Ouch, maybe trim them all to the shortest piece when the new trimmer shows? instead of tossing them. Or use them for practice setting it up?

Ordered one last week got it in less than a week. I still can’t figure out why I waited so long. It’s a game changer!

Morning J2,

That's probably what I'll do,as right now lengths are all over the place(twice fired and trimmed and 3 time fired and untrimmed).SAAMI calls for 2.724"(338LM),my shortest case is 2.709",longest is 2.745",and my chamber(Sinclair chamber length gauge)is 2.7495",so my longest case is still .005" shorter than my chamber.I may pick a number somewhere around SAAMI spec.(.025" less than my chamber and probably ideal for a carbon ring but I scrub it now after every range session of 30 rounds or so and keep it under control)and see if the shorter cases catch up after using them as foulers,etc.

Reading this thread has reminded me that I need to add a .308 cutting head for the F-Class 300WSM I just built this past July! ;)
