Could this be the BEST trimmer ever made??? #possibly

This little trimmer adapter made by Lee is my “go to” trim setup from now on...it’s a great addition to my Lyman Case Prep Xpress and if you’re tight on space for the reloading bench then this is the trimming solution for you! Super simple design and setup...it doesn’t get much better than that! Y’all have a good one!

I've been a reloader and shooter, both hunting and competitively for over 60 years. I don't claim to be any sort of expert but I have encountered a few things along the way in regards to reloading. I started by helping my dad reload in the late 1950's for his police revolver. Now to the subject at hand.

I've used the Lee trimmers for years BUT there's a step that must be addressed. The flashhole must be deburred first. The trimmer pilot ultimately comes to rest on the case head interior. However, if there are shards protruding on the inside of the case from the primer flashhole punching process the pilot is elevated above the inside head base producing a longer OAL. Additionally, if the flash hole is deburred too deeply the tapered end of the pilot will drop below the bases inner surface thus excessively trimming the case. That being said I do use the Lee pilot system but only after carefully deburring the inner flashhole lightly by hand to provide a uniform surface for the pilot to rest upon, making sure the deburred divet is kept as small as possible. But cartridge case head thicknesses often vary widely even among the same brand and lot as well. The principle behind trimming is to obtain a uniform case neck length for correct bullet tension as well as preventing the case mouth from jamming itself against the chambers forward surface ( OAL). The length of the case neck, shoulder setback and the overall case length are all critical to a great degree to produce the most consistent and accurate loads. By using the shoulder headspace datum point and the case head base as trimming reference irregularities incurred with the pilot trimming process are minimized.

I do use the Lee pilot trimmers on rounds I load for both plinking and close range hunting, usually as a time saving move. For my match and long range hunting rounds I use an LE Wilson, Hornady or Redding micrometer adjustable trimmer to eliminate any irregularities with flashhole or case head thicknesses to produce identical round to round loads that usually produce 1/4 - 1/2 MOA groups all day long.

Lee makes good products and the majority of the dies that I use are Lee and they produce excellent and truly accurate ammunition. It's attention to the little nit picky things that make the difference ultimately.

Just wanted to say thankyou, holy cow this is how to go.

I'll say these case prep centers are a game changer when you have ALOT of ammo to build, saves time.

I used these Lee trimmers when I had first stated reloading as they are economical and very accurate in consistency. Then I moved onto a Forester lathe trimmer.. that's just a little more consistent.. Recently I've been using the Lee quick trim. Have only one die for it right now and that's the grendel. I think I like that more then all as it does all 3 steps in trimming.
Enough rambling.. good video on the Lee trimmer.

Hey hey fellow alabamian here, first off I love see Bama folks on the interwebs. Let's me know we aren't forgotten. 2nd, I'm bout 7.5 hrs south of Huntsville. Anyways, this is awesome idea. It'll save a lot of money if your looking to load only specific calibers.

Coming to this
I hope you still read comments!
This is very much appreciated! I'm thinking about a 300 hamr, not exactly a standard round! I want to cut the cases down and trim from 556 brass, but didn't want to spend a ton on a trimmer for this one caliber. $30 in additoon to exisitng equipment will get me trimmed. Thanks😊!

Hey I'm a Mfg Engineer too😁. Great video and I've used the Lee cutter for years and am very happy with it for a couple of reasons. I love cranking out bolt action accurate ammo. To achieve that I have learned that I need to keep it simple and keep it repeatable. The Lee trimmer requires no adjustments. What you see is what you get and what you get is consistency. I don't need adjustability and actually don't want it. When I get my reamer ground for new barrels, I make the neck 010in longer than the tools trim length and it has worked flawlessly. Thanks for the demo!

i saw this guy earlier : chat And Prep - Lyman Case Prep Express + Lee Case Length Gauge And Lock Stud - 5.56 Lake City Brass - and he did it too.. between YOU and HIM, I am convinced now, to do this exact thing. I think it is a great idea and time saver!! great video

[razorbackpiperguy]

This is great. I always used the Lee trimmers but didn't like doing them by hand or putting them on a drill. Even though I don't like it, that's how I do it because I hate having to dial in a trim length every time I switch cartridges. I will be doing this. I've been wanting a prep center anyway. This is icing on the cake.

[tiresburn]

I went this route about a year ago. It is consistent and fast. I trim my 357 and 38 spl and the diff in accuracy is amazing. Good job putting this out for everybody to see.

[gopher_topher]

You're a hero, Thank you! I ordered this and its arriving any day now. I'm about to go nuts on some 223!

[shagitup]

Great stuff! Thank you! I was looking at the case trimmer express by Lyman at 150 bucks, but this is changing my mind since I already have the case prep station.

[henryian]

Tanks for posting, seems like a more sufficient way to prep casings.

[bigrod]

Great idea, this is a great video, you are exactly right, trimming off the shoulder is not as accurate, fast maybe but that's it, I'm using the lee one chucked in my dewalt ¹/4" driver, but have over 1000 to do, it's do dang slow, this may be a better move. thanks for great video

[THAS]

Thanks man! Just ordered one for my Lyman case prep!

[takinisurvivalchannel]

Holy carp I can't believe I didn't know thank you.

[mckwilly]

i chuck my holder in a cordless and do the 3, trim deburr and cham, and during a good chat or how-to vid it goes pretty quick...yea simple is good 👍

[ocean]

I recently invested in the lee trimmer for my Lyman prep center and I love it since I use the reloading manual trim size so the trimmer tip was a little long so I used a file very lightly till I got the size I wanted

[acesup]

So the Mfg Engineer takes a bunch of different components and assembles them in such a fashion as to be easier, nice I like it. Then the Operating Engineer (me) comes along and assists with the process to make it run smoother... Go get one of those 4 in 1 T- handle screwdrivers and slide your lock stud into the handle, maybe it'll help a little, it gave me faster case changes and easier grip. My 2 cents 2 years late... a penny for each year (Inflation).

I took my lock stud and epoxy it into a wooden ball to make it easier to hold onto. Some people use GOLF balls to hold the lock stud, Uncle Jim has a video I think he epoxyed in a socket to hold his lock stud. But yeah this is great use of making the case prep center even more enjoyable to use.
