Re: Lee collet dies--inconsistant neck tension

Thanks for the replies everybody,I measured the outside
of the cases and resized 5 more, each case sized ok.
I turned the die another 1/4 turn in and that small amount helped.
I'm reloading once shot winchester brass for incremental load developement
>>each case gets 1/10th grain more than the last to find the sweet spot.
When i found the inconsistent neck pressure >> my thoughts were -alot of good this will do.
My reloading bench is an old desk with a flimsy edge
where the press is mounted -it looks like it might
break with the pressure applied to the press.
I'm going to brace it off a bit to get a more solid feel.
If that doesn't give me consistant necks then i'll pull
the die apart and measure as stated above.
So far i like the little lee set-up , i know there
is more better equipment but hopefully this varmint hunter
can get by for now.Thanks again..Mike

Re: Lee collet dies--inconsistant neck tension

a johnny come lately here but i will stand with Jerry and Abinok as I have been using the Lee dies for around 2000 rounds or so now and i HAVE TO SAY AGAIN , " WHATS NOT TO LIKE " Sorry , just noticed the caps lock was on : )

Let me add that I HAVE all the high dollar dies ,and do not see any tighter groups with them. I have asked this before but since it has come up again I will ask again, Have you used / compared before you post ? I have also pointed out that a 1k champion has used the Lee dies to arrive there .

Re: Lee collet dies--inconsistant neck tension

Ol' Mike ,
Not sure whether you got the same instructions as I did with my Lee collet dies but it's all explained in there .
Lee advise that to adjust properly you must run the die into the press until it touches the shellholder plus 2 full turns . A minimum of 25 pounds of force must be applied at the end of the press stroke to properly size the necks . If that doesn't work adjust the die down another 1/4 turn . Lee also recommend that you size the neck twice , rotating the case 180 degrees between sizings .
If you want tighter neck tension they advise to either polish the decapper mandrel .001 smaller or order an undersize mandrel from the factory .
I have only one Lee collet die but think it's crash hot .

Re: Lee collet dies--inconsistant neck tension

The Lee collet neck die is all I use for neck sizing. In fact, it's all I use for sizing, period. When my brass gets too large to chamber, which is usually 6 or 7 loadings, I toss it and start over with a new batch. I haven't used a full length die in 3 or 4 years. If I do need to move the shoulder back a bit, I use a Redding body die, but this is very rare.

The Lee die is not perfect, however. I have found that they perform quite a bit better if I polish the collet and collet sleeve where they contact each other and apply a dab of grease around the mouth of the sleeve. From the factory there is often an excess of tooling marks and when these are removed the die operates to it's full potential.

Re: Lee collet dies--inconsistant neck tension

Bushchook,
Your post rang a bell ! I should have read more closely what jerry and abinok wrote .

The instructions say to turn til touching shl-hldr then 1 full turn.On down it speaks of "other" press's that can toggle over.-----Then it says 2 full turns after touching the shl-hldr.
The lever is out there where i can feel what i'm doing now[like Jerry said].
Looks like my load developement might have some inconsistent rounds as far as neck pressure ,but i'll give them a go anyway.Hopefully it will get me in the ballpark for a good load.. Mike
