Default Power Trimmer for 5.56 NATO (aka it's Chad's fault)

Generally when it comes to firearms and reloading, I get the blame, but this
time it is Chad's fault.

So Chad has these (yes plural) Dillon power trimmers for use on his fancy
Dillon presses. Since all my presses are green and red, you know I don’t
have the money for that fancy blue paint.

I was thinking that the motors on Dillon power trimmers are not much more
than a router/trimmer motor and I can use that. Next how do I hold it over
a case in a die and what die do I make, etc. etc.

So long story cut short. I came up with the follow ideas.
  1. Just buy and use the Dillon power trimmer die for the proto-type.
  2. Use a standard end mill and reduce the shank for use in the trimmer router, ¼” shank needed.
  3. Build a die to router adapter.

So I ‘started’ on this project last winter and as in started I made some
drawings. This weekend I actually finally cut some metal. Fast progress
for me. I still need to cut the plate and weld then test.

This might actually be a marketable product.

Hmm...interesting. I think I see exactly where you are going. I just bought the Dillon RT1200 and slapped it on my Lee Turret. No lathe.....yet.

You planning on a shop vac attachment point yes? Makes a mess.

Rich? Hardly. It was 10 years ago and only 180 clams on sale. I got the trim dies from another guy. I was up and running in a week at least.

This "rich guy" has probably trimmed 25,000 cases with his Dillon RT1200 just during the time you were making drawings. And I feed them through the automatic casefeeder in the XL650 press so that all I do is turn on the vacuum, turn on the trimmer, and get a sized and trimmed case ejected into a bin with every crank of the handle.

By all means, I don't want to discourage anyone from doing it themselves or marketing a different way to do it with things they made, but for many of us, some things truly are worth what we paid for them, and have nothing to do with being "rich."

$331 for the case trimmer. Hell I can get a 5 station Lee progressive press for that including the dies and case feeder...

It was kinda funny, I saw the title, 'power trimmer for 5.56' and the first thing I thought was 'what's a weedeater got to do with guns?'...

I gotta get out more--

And it won't trim.

Their new trimmer (RT1500) is more expensive than the one I have. But it's a lot more powerful so it can be also used for a lifetime of trimming down cases being converted from other cases. They should have kept the standard one (RT1200) in the inventory, too. Not everybody is making .300 Blackout cases all day long.

That said, Lee makes great stuff at a great value. I have a lot of it, and some of their items are the best of their kind, like their pistol Factory Crimp dies. I've used them to fix ammo that came through a Dillon die. It's replaced the Dillon in the crimp station for the .45 toolhead.

The nice thing about building one will be making it more convenient to setup, probably. I only trim .223, .300 BLK, and .308 with the Dillon power trimmer. Everything else is small enough batches that I use a Makita drill powering the RCBS hand trimmer.
