Lee Collet Neck Sizing Die ?

[billt]

I just ordered and got one of these dies from Midway in .300 Win. Mag. Has anyone else used these? I'm wondering about lubing the inside of the case neck? It should still be required since the expander ball is going to be pulled through it on the way out, correct?

Have any of you experienced any better accuracy segregating your brass to a given rifle, then just neck sizing them with this die? Bill T.

When I was using that die set (.303 Brit) I tried it both ways and it did not seem to really matter.  I found it to be much easier than full length sizing.  I know the brass certainly lasted longer.

No matter what the size, every time I've had to deal with a stuck case, it's because I didn't lube the inside of the neck.
I always do it, no matter what brand dies I'm using.

You don't need to lube up the collet die. It basically squished the next back down around a center mandrel with force from the outside collet "fingers". The is no real expander ball. You can see a picture of it on the Lee web page: http://www.leeprecision.com/cgi/catalog/browse.cgi?1272818086.1748=/html/catalog/dies-collet.html

Once the die is apart, you can see there is not really an expander ball. Just a rod or mandrel for the collet to press against. I'm going to try this die with some once fired brass from my Kimber 8400 Police Tactical. Hopefully it will produce a little better accuracy than full length resizing. We shall see.  Bill T.

after buying an RCBS gage for out of roundness (concentricity gage), I use the Lee Collet dies for everything.  They consistantly produce necks under .002-.003.  I had to get a redding small base body die for ,223 because of chamering problems.  The lee die is only sizing the neck, and all  calibers will start to chamber with difficulty as the brass grows and the shoulder moves forward with repeat firing.  I set the shoulder back about every third loading with my 300 win mag.  In my experience, I have found the lee dies to produce my most accurate rounds.
