Neck sizing with a full length die

I agree that 4 turns seems like to much.

Prior to buying a neck sizing die I had used my FL dies to neck size. Not sure how many turns but you can just experiment till you find what works, watch how the lube marks on the neck to see how far down you want the die to effect the neck. Or paint the neck with a sharpie and that should show how far the die is traveling on the case.

My guess would be 1 to 3/4 turns back but you would need to find that by trial and error.
 
I've heard - but never done - that if you can fit a dime between the shell holder and the die you're in the neighbourhood.

I've got a neck die inbound.
 
The best way to neck size brass is to neck size about 1/2 to 2/3 of the neck. This provides enough tension to hold the bullet, minimizes working the brass, and allows the bullet to stay concentric to the bore (assuming your chamber is cut straight). Start with the die out and keep turning it in until the ram is all the way to the top and only half to 2/3 of the neck is sized, set the lock nut and you're good to go. Nk sizing dies are a waste of cash unless your using a bushing die a FL sizer will do both jobs.

Depending on caliber of course!
Some use the complete neck to support the bullet (eg .300S) so you would just back off the FLS die just enough to not contact the shoulder when sizing.
 
I just use a white board marker, put a line down the neck of your casing. Screw the die a ways out, then test in small increments as you screw the die back down until you have enough neck resized. As your marker erases on the case that is how far down the neck you have sized.
Clear as mud
 
But you still have to push the brass up enough to get the primer to come out. Can you lower the deprimer rod on Lee dies to make this work?
 
Yes, loosen the top nut/collet and push the decapping/sizing rod down to the depth you like.

Senior: the complete neck is not required (for any calibre) to hold the bullet. Unless the bullet is literally hanging out of the neck because you are trying to reach the lands in which case you need to seat deeper, sizing half the neck will provide enough tension to support the bullet from coming out.
 
I use FL dies to neck size (about 2/3rds of the neck) all the time. No problems with doing this with a handful of calibers I've tried. I just did 60 rounds of 303 British today this way actually...
 
You know what, I actually managed to neck size my .303 british rounds tonight with a full length sizing die, and I barely touched the shoulder on the thing. I don't think I'm going to bother with a neck sizing die, this seems to be working out well :)

No particular calibre maybe, but possibly some bullets. If you are loading TSX or TTSX you may need the whole neck sized, to provide enough tension. The grooves that are cut in the bullet reduce the surface area that touches the neck by almost 50%...
