    I have adjusted my collett die the way Lee says. And then moved the die up and down . and I am not getting very much tension to hold the bullett. My 30'06 will hold a bullett but not really snug. M 25'06 will not hold at all. I thought ABinok wrote once about different mandrels or collets but I can't recall. Jerry Teo wrote about 4-5 thousands tension to hold the bullet during recoil but I am not getting this. Have a great Christmas and great New Year. Shawn

    Not sure on the Lee neck die,but if its like the redding bushing dies,the dies dont come with the bushings,you have to buy them individually.

    I chucked my mine in a drill and used oiled up sandpaper to take it down about .001 to give more tension. If i want more tension than .002 I use my redding die. I think if you took more than .001 off a lee die your going to have concentricity problems ( or however the hell you spell it)

    Is your brass work hardened and in need of annealing?

    Call Lee

    Shawn,

    You'll need to call Lee directly to order the smaller sized mandrels @ about $4.00 each plus shipping. The standard "decap mandrel" is sized .3055" for the 30-06. You'll want something like .3045". I have several, 3045" and 3035".

    My brass is once fired. I don't know about annealing. I readjusted everything and put more pressure and am getting about .003-.004 on the inside .308-10 before starting .304-5 after this is measured with a dial caliper on the inside of mouth. I measured my 243 that I use a standard redding nck sizer on and I get about .005 when measured the same way. It just seems a little looser on the collett dies. but the numbers are right.

    Thanks.

    Die instructions

    Shawn,

    If I recall, don't follow Lee's instrucitons to the letter. Try adjusting the die up or down with a case inserted. You want the die adjusted so that when you just about hit the bottom of the press' stroke, the die sort of pops. If you have a weak bench, you'll know when you hit that point 'cause all sorts of stuff on your bench will jump or fall over. Might save you $4 plus shipping for a new mandrel.

    Exactly!
    You will know you are there when as you pull the case off the mandrel, you hear a sucking sound, and a pop, as it clears the case mouth.
