hi,
is the case length crucial for the lee neck size die ,the collet one, to work effectively?

as in, i think some of my 30-06 cases were trimmed down to ?? length , or a bit shorter than min trim 30-06. an im finding not every case is closing up tight enough to hold the projectile in place.

wat i did was use a FLS with no stem and jam it up just ever so slightly to close the neck, before i seated. worked but id rather not the extra step and wondered, How did the Leee collet work in laymens, and ideally, longer cases r going to crimp better through this ?


i did measure some cases, 2.48s worked, 2.47s didnt seem too

i guess ive answered a bit of this but questionin the lee collet n how it works etc
 
The Lee collet doesn’t care how long the neck of the case is. They’re actuated at the base via an internal sleeve. I guess it could potentially be too long, but I’d assume they left a reasonable amount of space for excessive neck length. There’s also space for a drastically bumped out shoulder from what I can see in the actual crimp marks.

what might be 'over sized' internally to not size some down far enough?

i'll load up another 20 or so tomorrow and see how many dont close enough.
 
More likely operator error, or your press not quite set up properly - ask me how I know... Most folk bump the case twice, rotating the case 180 degrees between bumps.
 
"operator error" was certainly my experience with it - was trying to improve my 7x57 loadings for a Ruger #1 - I just could not get dependable neck sizing to occur with the Lee Neck collet sizer - was definitely me and the pressure required on my single leverage press - I gave up and went back to using RCBS Full Length size die, but did a "partial sizing" - set the die so was about .050" (1.5 mm) clearance between bottom of die and top face of shell holder - could see the neck was not being sized all the way to the shoulder junction - about every 3rd or 4th load or so, I would "bump" the shoulder back a bit by reducing the "gap" between die and shell holder at top of the stroke, because those fired cases would get to be fairly "snug" to try to re-chamber.

In hind sight - I was not peeling the case necks to all be same thickness - so makes sense to me now, that some needed more or less pressure to squish down to be tight on the internal mandrel rod of that Lee Collet Neck Size die. I never could see difference in grouping on 100 yard targets, so decided that the commotion was simply not worth it for that rifle and me. For probably the last 5 or 6 years of deer hunting with it, I just did Full Length sizing - checked over-all length of case each time with a Lee Gauge and trimmer tool, and loaded them up - worked fine.

That was part of my experience that helped me understand might be difference between a hunter's need for a single shot from a clean cold barrel, with perhaps a second follow-up shot, versus a target guy who will use warm-up and sighting in shots, and then go for multiple three or 5 shot groups on targets for score - I no longer believe that both "games" lead to same the re-loading needs.

yeah copy- i was twistin them 180 also incase that helped.
seemed to think no matter how much harder i went without going 'too' hard, it didnt seem to close a few, maybe as potash said case neck thickness or something.

Nels, i wrecked a friends FLS he lent me, so i bought this 2nd hand online as ill keep the neck, an seater, he can have the FLS back lol... i am totally aware of the PFLS an am a fan, im just down the FLS although i will more than likely make do with the 308 FLS and just partial the neck , which does the job as long as you dont play with shoulders...... ask me how i know... lol.

that can be a drastic measure for cases that wont play, i do however have something like 100 or 2 of S&B brass to try pick a good few dozens
 
Maybe is a typo, but if using 308 Win dies to re-size 30-06 necks (first Post versus Post #6) - as per drawings, I think 308 Win is about .004" thicker at neck with bullet seated, then is a 30-06? So, if sizing with an expander ball - from inside the neck - then likely works fine? But if pressing from outside of the case - like the Lee Collet Neck Size - will take more pressure from press to squish down 308 Win versus 30-06 - if the mandrel is the same size?? Not sure how significant, but case mouth to shoulder junction is longer on 30-06 than on 308 Win - like .395" versus .304"? How I think collet and mandrel would work together - not real certain that the inside of the collet diameter for 308 Win, is same size as inside diameter of the collet for 30-06 necks, since specs for case neck thickness are not the same?? Might be part of the issue that you are having?

no thats right, a 308 full length size.
thats right regarding neck length, You set the die up so the neck goes in a desired amount. We are not talking about jamming 3006s up a 308 Die.

any minor differences in the "millimeters" of neck in which a Thou matters, will be blown to size the moment primer strikes- its complicated..

Youre on another page Re the 308 /30-06 mix up, All good NVM the whole subject in which I've thrown the 308 into the mix lol

Im using a LEE collet deluxe kit 30-06 Neck die i believe is a "D9" to Stick Sellior And Bellot stamped factory Once Fired .30-06 Springfield brass, via a Lee anniversary kit reloading Press-

as a matter of fact ill be back in 10 minutes with 20 cases and see how many issues in the mix.
 
Verdict:

User Error 99% and 1% Brass issue.

So a couple of the very short Cases may of been the issue and When I would stroke the Lee press to Reclamp the Brass, looking back I was not fully allowing the brass to open, reset then Jam back in the Die.

so i think i kept pressure on the die in one motion, even tho i was doing 2 motions down per se.

once i stroke it down, and back up, release ,rotate and stroke again with not Alot of force but with force, I end up with a Tight neck tension........


Apologies.

Thanks!
