Does anyone market a Pneumatic de-rimer?
Thank you

I would suspect most would want the feel of whats going on.

[Ajax111]

You may be right. Maybe a Winter project

I have one that uses explosions to remove primers.

If you get one, make sure to have a good stock of replacement pins
if you ever run range brass through it without inspecting each one.
You'll need a new pin for each piece of Berdan primed brass you put try to de-prime.

He's talking about making jackets for Swaging, probably 22lr to .224 jackets, not sizing/de-priming cases.

If I'm not mistaken, I believe BTSniper has made some in the past. Check with him.

Opps.
I thought it was another case of one of us old guys not wearing their glasses or proof reading.

I haven't found a lot of Berdan primed 22 Long rifle Or maybe it all is?

I'll check with BT.

Thank you

I was going to say something, but I figured I had made my fair number of mistakes by not thoroughly reading a post.

Myself and Duke in Florida built one several years ago to derim 22 LR, Worked great. I posted a video around 2014 on this theard, but I can’t find it. I’ll post it if I can find it, Duke is gone and I am upgrading it now to do 5.7x28 so it is out of service right now.

Remember compressed air is a expansive media. After the rim is ironed out all resistance is gone.
The compressed air will slam the ram into the derimming die and beat the end like a mushroom.
And if your fingers are in there it will smash them to.
Better to use a hydraulic setup.

Pee Wee , I did find the video on you tube.
Thank you again.

[Pee Wee]

Ok great, I can’t find it , what is its title, I thought it was Duke in Florida derimer

[Ajax111]

I typed in Pneumatic De Rimer and it came up.

[Pee Wee]

Ok thanks I found it, there is another one also showing the upgraded version with everything mounted up with duke running it and me talking.
