Dillon form and trim die for 300 fireball using RT1200
 

Does Dillon make these? If not, what needs to be modified to make it work?

Kevin

Contact CH4D. They make the Trim die.

Any idea what they are charging for that die?

CH4D makes the die and it isnt expensive, under $50 if I remember, but you might need to machine off some of the toolhead to allow the chips to be sucked away.

I milled about .350 off my 1050 toolhead to make it work.

You will have to machine a tool head for the hose attatchment to work. If you don't already have a RT1200, the Rapid Trim for 7.62x39 has a longer trimmer shaft and die and will work on unmodified toolhead. I beleive the 7.62x39 trim die needs to be shortened al little to trim brass to right length.

Yes, CH4D. I have one and they are under $60. Yes, you have to machine the toolhead.

or you can modify a .308 trim dies from dillon.

Damn. How far does your 300 Whisper brass protrude into the window on your CH4D die? Mine doesn't even make it into the window. I think they forgot to run the counterbore for the trimmer shaft deep enough so that the brass could be trimmed. My brass is 1.355 for reference...

Kevin

Mine comes in about .200 or so.

In reading all the 1200 trimmer threads, am I correc tin thinking that you need to mod a toolhead to use the std 1200 trimmer with a CH4D die, or you can buy the 7.62x39 1200 trimmer?

Is the x39 trimmer compatible with other Dillon dies or is it solely for x39 because of extended shaft?

I dont want to end up with a trimmer thats for 1 caliber only

Dillon told me the 7.62x39 trimmer was could only be used for that one. I'ld contact Dillon and make sure that hasn't changed though.

I ended up buying an extended Redding shellholder and using my Rockchucker for making my Fireball brass. Sucks, but at least I can do it.

Kevin

I need to run it in a Dillon 650 but dont want a trimmer only for Whisper cases.

Am i right in thinking that modding a tool head and using a CH4D die will allow a std trimmer to be used??

You do need to mod the toolhead.

I hated chopping on a 1050 toolhead, but it was for the greater good.

For use with a std trimmer and CH die or a x39 trimmer setup?

Can anyone verify if the CH die with a standard trimmer works in a Hornady LNL AP or will i need an extended shell holder and my single stage?

The CH4D die will not work with the standard trimmer and Hornady LNL. This is the EXACT setup I have, and had to go with the Redding extended shellholder and my RCBS Rockchucker press for my brass forming operation.

Kevin

That's a bummer. I had these grand dreams of progressive case forming with lube dies and all kinds of wonderment.:mad:

I've got a 1050 and the ch4d trim die, but I'm not sure how much to machine off the top of the tool head.

Do I need to take .350" off the entire top or just enough for clearance for the plastic vacuum attachment around one of the stations?

Also... does that .350" account for leaving threads exposed on the die for the knurled lock nut to engage?

pictures of yalls set up would be nice...:o

You and me both. I was hoping for the proverbial "poop through a goose" rate of forming brass.

Kevin

Effectively destroying a Dillon 1050 toolhead isnt a cheap decision. The trimmer and form die are not cheap either.

Then when you factor in the cost a new trimmer every couple months and new carbide trimmer blades every 10-15K pcs or a *single* piece of steel cased brass, it gets even worse.

There is a reason why I am kinda picky when I say processed/sized brass will not work. Every trimmer I have killed went that way. And it takes under a second or two.

But it did give me an excuse to buy another 1050.

MAN CAVE Heaven!!!!!!

This is the reloading equivalent to Charlton Heston's gun collection...

Kevin

"Thou shalt not covet"...

"Thou shalt not covet"...

"Thou shalt not covet"...

now that's a reloading room.

I've got a RCBS Jr, an old Pacific semi-progressive shotgun press, and an older dillon 1050.

And it looks like I'm about buy a new tool head for the 1050 to be the sacrificial lamb for my .300 whisper trim die. Yeah, $190 seems kind of excessive, but I've got plenty of good .300 whisper candidates...


Hoser, how did a single steel case destroy your trim die? If it just galled the neck or something, you might try chucking the die up in a lathe and polishing it with some fine emory cloth in a slotted dowel. At least, that's what the guy over at CH4D suggested.

Steel cased crap make short work of the cutter blade. The trimmer bogs down, but it does not kill it.

Things like that are why I have not had the guts to hook up a motor to my 1050 for processing brass. I can keep an eye on every piece of brass and I can feel how each one cuts. Most of the bad ones get culled by feel while forming. After they come out of the tumbler I inspect them all and usually dont find very many.

The pictures of your loading bench are nice and all, but how about some close-ups of what you had to modify on the toolhead / shellplate to get the .300W trimmer to work?

I'm planning on getting a Dillon trimmer in the near future, and making .300W brass on my 650 is one of the primary reasons.

Thanks.

We're kind of asking a businessman to divulge his manufacturing secrets here. I understand if we don't get detailed pics and a how-to...

Then having not seen the dies (or the Dillon trimmer for that matter), I may have misunderstood. I assumed what you get is a sizing die and a set of cutters, and that to use them you have to modify your own toolhead and/or shellplate.

Hence, me wanting to know what needs to be done, what works, not reinvent the wheel, etc.

If someone sells a complete setup, I'm good with that too.

Honestly, I'm probably just going to take my new toolhead when it comes in along with the trim die, motor, and vacuum attachment down to the local machinist in town and work with him on it.

He's got better measuring equipment than I do, anyways.


As far as automation, I just got done hacking up a treadmill to run my dillon, but I've been doing hand sorts before loading the case feed hopper. Not too worried about burning up a cutter.

One more quick question about the CH die, is it adjusted like the standard Dillon trim dies? Screw it down till it touches the shell plate and then back off a quarter turn?

good question.

one way to find out would be to do that, adjust the motor depth, run a case through, then measure the neck length and compare it to spec.

Of course, I've heard some pretty wildly ranging numbers on what spec neck length is.

So the Std Dillon 1200 with CH4D die and a modded 650 toolhead is the combo

ie NOT the 7.62x39 trimmer which is specific to that case only?

Tag for future info...

Yes, Spanners. Use the standard Dillon trimmer motor (so you can trim other calibers later) and modify a $25 toolhead to accommodate the CH4D 300 Whisper trim die.

Cheers
Do you have a part number or a link - I cant find it on their site.

And then I just have to get CH4D to ship to New Zealandisatn :rolleyes:

Does anyone have a picture of how they modified a Dillon 550 or 650 toolhead? When I screw in my CH4D die it looks like I would have to mill off about 1/2 the thickness of the tool head to put on the vac attatchment.

tool head modafications
 

Second for pictures of the modadied 650tool head

ANyone able to confirm the amount to be milled off 550 or 650 tool head?

If you mill down to the flange, more than 1/2 of the trim die window is above the tool head. The 650 with the deck cut works great with the vacuum attachment.

https://sites.google.com/site/xr650r..._Milled_01.jpg

The 550, if you cut the entire deck down, the other dies positions are hard to use, and there is not much room for die lock nuts under the press due to the indexer. A pocket cut down to the flange works, and then a 1/4 pocket under that station so you can place the trim die lock nut under the toolhead. I've compared many different 550's and some had a 1/4 inch difference in clearance between the bottom of the toolhead and the indexer.

https://sites.google.com/site/xr650r...2/550TH_09.jpg

These for the 650 or 550 are $50 plus shipping.

Once you set up for trimming, take care of your Motor, cutting the blackout make LOTS of heat.
