what size to set lee collet die youtube

• #1

Anyone ever done this? The pin floats in the dice so what I'grand thinking is but put the die upwards some then that it doesn't use the collet on the cervix. The order I'm thinking most right at present is:

-Universal decapper (flash hole bank check)
-resize (no expander)
-size neck (collet dice equally mandrel)
-Charge (probably a habitation brewed charging dice)
-seating

I may eliminate the universal decapper by eliminating the expansion function (apply a 223 expander or turn it off) of a standard sizing dice. The other thing is that this setup would exist compatible with my LNL AP as a "one shot" system where I wouldn't need to use the press twice. I'd just throw deprimed/cleaned/pocked prepped contumely in and run.

The merely consideration I have that could significantly alter this is that I wouldn't have trimmed and I recall I need to practice that after the case is in its final shape. (e.g. betwixt cervix sizing and charging.) If that'south the case then I may take the starting time steps and have another setup for the last two steps (iii if FCD is used) and I would probably end up on my Dillon 550.

Am I going up the wrong tree hither? If the shape of the collet dice's pin is a bit suboptimal that's non much of a business organisation every bit I'll merely chuck er up in the lathe and do what I demand to.

I'm going to practise FL and so employ the collet die every bit an expander.

• #v

I have been experimenting with this a flake lately,FLS without expander ball is kind of like a poor mans torso die and has been working well enough in conjunction with a lee collet die. Another bonus is y'all don't demand to lube inside the neck, merely castor out the loose soot and you can expand/seat away.

Castor out neck.
Lube cases.
FLS (shoulder bump) without expander ball.
Expand neck and decap with lee collet die set to a lite clasp on the neck.
Prime.
Add powder.
Seat bullet.
Wipe off lube and inspect assembled round.
Washed.

I have lost no measurable consistency so far past doing it this way.

That'southward interesting and it doesn't sound birthday different from what I'm proposing to exercise. Where do yous trim your brass at if you don't heed me asking? It also sounds as if you're pretty well eschewing cleaning also?

• #9

Pretty much u just use body dies so lee collet dies.

I use the same process. Only I apply the lee collet, so the Redding body die. Works bang-up!

• #ten

Pretty much u only apply torso dies then lee collet dies.
That'southward what I do for the last v years.

I measure out information technology with concentricity gauges and consequence were 0.001~0.002 runout

i sold all my bushing FL dies afterward~

Accept you had any issues doing information technology in that gild? I used to bump with a body die followed past the collet die and contumely that would chamber after bumping, I would no longer be able to close the commodities on later the collet die. Switched to collet die first and then the body die and my issues went away.

That'south interesting and it doesn't sound altogether different from what I'm proposing to do. Where do you trim your contumely at if you don't mind me asking? It also sounds every bit if you're pretty well eschewing cleaning as well?

Brass trim (if it needs it) is washed after FLS and collet mandrel, I have castings of several of my chambers and virgin brass necks are commonly quite a way brusk of actual cervix in the chamber. Considering of this I don't trim to SAAMI spec and continue neck length just short of my sleeping room, depending on brass quality and cartridge being shot this can mean brass gives out before regular trimming becomes necessary, but yous practice need to know YOUR chamber.

I don't have the ability to trim brass based off a shoulder datum, so trimming based on overall brass length AFTER complete sizing keeps necks a lot more than consistent than trim before sizing in my experience.

For cleaning my contumely all I do is squirt a bunch of fired cases with carb cleaner and scrub them effectually in a rag, which is mainly to ensure there is no grit or marker residue to scratch up my dies or stick cases.
Inside of cases practise not get touched autonomously from a brush through the neck and a quick tap on the demote to dislodge loose carbon.

Primer pockets are a 50/l matter. I usually don't bother, merely sometimes I feel guilty and scrape the soot out. I can't say clean pockets shoot any more consistently than fouled pockets.

I usually shoot steel rather than paper groups, but can say my current (lack of) cleaning regime has not measurably increased my group sizes ane bit.

Have you had any issues doing information technology in that order? I used to bump with a torso die followed by the collet die and brass that would chamber after bumping, I would no longer be able to close the commodities on after the collet dice. Switched to collet die first and then the body die and my issues went abroad.

Depending on how close you bump your shoulder and exactly how you measure your base to shoulder datum, collet sizing later FLS/body sizing can motility the shoulder out as much every bit .003-.004 from non cervix sized brass. One time this value is known (and known to be repeatable) y'all can bump your shoulders back further and let the collet dice move them out again.

• #15

Push downwards too hard on a collet dice and y'all can collapse the neck and shoulder completely.

That is not at all how collet dies work. Push down too difficult and you can stick a instance yes, only you cannot plummet the shoulder with an in spec die.

• #17

dumb question, I discover some of you mention a "shoulder die." I'm presuming that's a FL die where the neck portion is oversized compared to the contumely so it doesn't alter it?

Thinking I'd try to accept a 243 sizing dice to the Atlas and make that happen but may but past a 7-08 die trunk instead. I have a feeling that a die body wouldn't be the nearly pleasent affair in the world to have HSS to, mayhap even Cobalt.

I may not be following this correctly .
This is to employ a mandrell and instead of using the mandrell die.

I take a sinclair 308 mandrell on back order and a sinclair mandrell die.

The lee collet not being used can just have the collet removed.

Simply the expander is 305 and I got the Sinclair ordered at 306.

I have a sinclair 308 mandrell on dorsum order and a sinclair mandrell die.

But the expander is 305 and I got the Sinclair ordered at 306.

Dont know how accurate I could remove .001, have done information technology on expander buttons .

Lee shows a PN for a .3035 pin just non a .305 one in their nether sized mandrels. According to their web site the standard mandrel is .3055

You may be able to do something similar that with a shear tool in a lathe (afterward annealing then re-hardening when you lot're done cutting unless y'all were using carbide) but I would think you'd be talking almost a piece of basis rod honestly.

• #22

Start of all every bit usual I was thinking backwards, so I removed the last stupid sentance from my post.

I measured the pin in the collet dice over again and got .305 but my calipers only go to .0005 and so that's ok.

With fc gmm brass the effect from the fls die is .003 nt. I was wanting to get to the magic .002 nt to become an extra 500 yards out of it.

Lol

Really because .002 nt seems to be the most popular standard here on the hide and done with a mandrell floating. That .003 nt is measuring neck before and after seating bullets.

I don't mind going to the extra step for my sons 308 that shoots fgmm manufacturing plant rounds just below 3/four moa occasionally but speed and es and sd is poor.

I am practicing to beat it with these latest rounds loaded with cfe223 to add a piffling estrus under the 168 smk's.

He is supposed to group / chrono these this evening and I told him to spotter primers ect carefully.

• #23

FL sizing without expander followed by Lee collet would piece of work but you will as well exist working your brass more than you want to. I use a Redding body die to bump ii-3thou then Lee collet for 1.5-2thou neck tension with great results.

• #24

If you remove the collet and simply use expander I dont understand how information technology would work brass more?

• #25

If you remove the collet and but use expander I dont sympathise how it would piece of work brass more?

You work the neck in the die and the expander ball pushes it dorsum out typically.

• #26

I believe the object was to remove expander in fl die.
Remove collet from collet neck sizing dice and go out the epanding mandrell in that.

Or I am lost again.

• #29

Well mandrell then.

Wanting intent non tiny details.

Not tring to argue.

So for the moment my mandrell and expander are the aforementioned size.

Will I yet go a benefit from the carve up procedure due to the free floating?

All I use anymore is a lee collet and a trunk die.
Cheap, consequent and effective.

@Steel head May I inquire in what order practice you utilise them in? Cheers

Thanks flight, I capeesh the post.

• #35

Dumb question, I took my calipers and measured the outer case wall before and afterwards seating bullets. I was getting 1 thousandth with a Nosler Custom Contest. Should I be looking to order the under sized Lee Mandrel? By their specs it'due south 2 thousandths smaller. From what I've been reading I'thou probably short on neck tension. I was as well running united nations-annealed contumely if that makes a divergence (more spring back.)

• #36

Endeavour adjusting your die. I get more cervix tension past screwing in the Lee collet die.

• #37

You should also measure the thickness of your case neck to determine more authentic neck tension. Most instance neck thickness measures .0015 , only I came across some measure .0018. Always a good practise anneal after two firing.

Lee collet die is way underrated. You hardly hear people talk well-nigh it because information technology doesn't have the fancy name of "Bushing/ Micrometer /Competition"

Im proud of my Lee Collet dies. They're fantastic. They're always my final size step. I'll full length size to where is bumps the shoulder about .002" and so run information technology through the LCD to gear up my desired final neck tension. Anneal and trim every third firing. Easy cheesy. My buddies that have all the micrometer, contest, etc dies were surprised how my ammo is but as accurate as theirs.

Thanks. Lee must have just shipped a production run because they're now in stock everywhere. They've been OOS for months.

This.
