Case trimming with the LE Wilson micrometer case trimmer!

TheDomFather · Jan 14, 2018

Folks,
Quick video to show how I precision trim with the LE Wilson Micrometer case trimmer. Although slow this is very accurate and since there are not many reviews or videos out there I figured I would share.

Thanks,
Dom

Good video. How about a video showing how to trim pistol brass with the Wilson trimmer.

I do have the pistol shell holders. Next time I load up some .45 ACP I will shoot a video for you!

I have owned one of those for years.

Great trimmer.

To get a consistent crimp in crimp groove when using mixed brass.

Also for when you are using a taper crimp die, If your lengths vary your crimp will vary. Larry if I get a chance I will shoot a video for you today. Do you have a preference? I can do 9mm or .45 ACP?
Thanks,
Dom

Most folks do not trim handgun cases, primarily straight walled cases, used in handguns.

But, to get consistent ignition and accuracy on high pressure handgun rounds (357 Magnum, 44 Magnum, 460 S&W Magnum etc., etc., etc), a consistent crimp is necessary. To get a consistent crimp, a consistent length of the case is required.

I do not trim any of my cases used in semi-auto handgun ammunition. My full power 357 Magnum or 44 Magnum cases get trimmed but powder puff loads do not.

Either one is fine . Thanks

Those are nice trimmers! They are not really much slower that the other lathe type trimmers once you get used to it. I sprung for the carbide cutter for mine.

My Wilson has some age on it. It's about as precise as it gets.

I also like the Forster a lot.

That Wilson definitely has been put to good use. Micrometer makes my life simple

I bet.

The oxidation is from being on the range in the humidity overnight at Benchrest matches. Same reason my BR-30 has a tiny bit of surface rust here and there.

Hit it lightly with a bronze wire brush and put a thin coat of CLP or any thin oil on it will bring it back to new!

You are right leave it as is its more Nostalgic that way

lol....Now that it stays indoors I really should clean it up.

I like the “if you don’t know what chamfer and deburr is...” statement. That made my day.

Why don't they make the Wilson case holder out of stainless steel?

So you are specifically talking about cast lead bullets with crimp grooves

They could but the material is more expensive and stainless tends to be more difficult to machine. Both resulting in higher prices.

If I may, it also applies to jacketed bullets with canellures.

I do not trim any auto cases like 9MM, .40, .45 etc. I do trim revolver cases, unless I bought a batch of it and the lengths were very close, like I did with .32 Long, .32 Mag.... .38 Spl and .357 Mag range brass lengths are all over the place. I also chamfer and deburr anything that is trimmed.

Do you have to use an arbor press for inserting the pistol brass? That's gotta make for a slow trimming rate. In the Forester you just chuck it in the mandrel, tighten, and trim. The bottle-necked brass looks simple and relatively quick- but what about for straight-walled brass?

I will make a video for pistol brass to show you guys how it works. Its snowing and freezing here so my garage time has been limited but this weekend should warm up enough for me to get in there!
Thanks,
