Primer Pocket Swaging Idea

[dbarnhart]

Has anyone ever tried to make a primer pocket swaging tool that would screw into the Hornady LnL-AP in place of the primer seater punch?

I called Hornady today and passed the idea along to them but who knows if anything will happen or even if it is feasible.

I don't think there would be enough force that way.

Or you would damage the press exerting enough force. The shell plate attachment is not very strong. Adequate for what it is designed to do, but not with lots of extra factor of safety built in.

This is one reason why it is handy to have a good, stout single stage press around.

I agree you would damage the shell plate or something else. In a single stage you could swap out the shell holder for a mandrel that held the case and have a die that swages though.

Dillon 1050 swages on the press.

I know. That's what gave me the idea. I have the Dillon Super Swage 600 and it works great. If I could figure out a way to do it on the press it would save a step.

rcbs makes something similar. unless i misunderstand what you are talking about.

A 1050 has a station to swage this is what it looks like without a case. It is supported from inside as it is swaged from the bottom.

Yes they do.....for a single stage at least. I've used one for years...not that I've enjoyed it. The thing I don't like is that once the button is crammed into the pocket (swaged), pulling the thing out takes a lot of force. You have to give the press handle a running start....and sometimes it takes more than one hit (hit is descriptive) to unloose the button from the case.

I've always felt that the operation was hard on my Rock Chucker but it seems to hold up. That just plain wouldn't work on a progressive....like jmorris said, it would tear up the shell plate.

I've been amazed with the apparent ease with which the Dillon tool seems to work....without the leverage of a press....how do they do that?

I'm using RCBS's brand new military reamer for their Trim Mate now. Big improvement over their old pocket reamer. Also I find that the slight chamfer it leaves makes the brass easy to tell at a glance that it's ready-to-load military brass. (crimpless). I like that, personally, plus there's no pockets less swaged than others. Swaging can be a real rhythm stopper on a progressive, especially on really old and hard LC brass.

jmorris: I love that big honkin thing, but I'd have to have my RCBS progressive too....for the other calibers.....the real problem for me is not the affordability of the big Dillon.....it's being able to buy all the components to feed both monsters!

Take it apart and look at how it operates. More leverage than you would think...and butter smooth.

swagging the primer pocket?
What is the desired effect?
Could you please further explain?
Thanks.

 

[jmorris]

The point is to remove the crimp found on "military" brass. It also ensures a nice pocket opening as you cannot feel primer seat on the 1050 (it's done on the down stroke). The "cam" on the 1050 also seems to have a lot more leverage than the overcenter link found on other progressives at the end of the stroke.

 

[jmorris]

Also, the swage rod on the 1050 is on it's own cam too.

It is a nice idea but I wonder how much swagging can be useful w/o deforming the head of the case.
What I do for years is to run them one by one in the motorized RCBS prep station and cut a tad from the pocket.
I use the lee cutting tool to size it too pretty similar setup to this person....

When I tried other things I always run into issues with the primer seating.
Some cases/calibers are more forgiving than others though.

Cheers.

You'll make the pocket too large before you damage the case head.

Yeah, Iv'e seen it work in videos....hell, I may still buy one...they are trick for sure. Besides, what's one more way to decrimp military cases.....that would make 4 for me.

The only flaw with the Dillon is the need for readjustments for different brass.....that's not necessary on a good reamer like the new RCBS one.

RCBS has a "new" reamer?

 

[amlevin]

Unless there is support from the inside of the case you run the risk of damaging the case head (extractor groove) or the shell holder. The RCBS and Dillon swaging tools both use a backup tool that fits inside the case while the "punch" is being inserted into the primer pocket.

Yes.

The old Trim Mate tool looked like this:-------------------------------------->The new one is this:

Unfortunately, Midway still sells both, because they must still have a bunch of the old ones (on sale of course). However don't fall for it. The new ones don't remove near the brass and don't leave the infamous giant chamfer.
