I have been getting good results from using the inexpensive Lee sizing dies but get noticible "scratches' when using the neck sizing die. Part of me assumes the natural progression is to move up to a more expensive die but what little research I have done shows that the Lee die may be as good as I need it??

Thoughts?
 
Yes - the deluxe three die set with the collet neck sizer. I was prompted by your reply to take it apart and clean it up but still, following the instructions I get marks the entire lenght of the neck. Not so deep that you can feel them but visible. Every mil around the entire case. One pass only.
 
Have you tried to lubricate the neck with mica or graphite? Scratching usually results from too dry a contact, assuming good quality dies and Lee dies are fine.
 
Is it 4 pairs of vertical lines spaced equally around the neck? That's likely from the collet closing, and it's pretty common; I get the same with mine.

I upgraded to a set of Redding Competition dies last year and I'll never go back.
 
You may also simply be seeing the lines that the collet puts on the neck. There should be 4 lines (I think 4 anyways) at regular intervals around the neck simply due to the collet design.
 
if it was four i would have zeroed in on the collet as well but they are every mil all way round (10+)

i will make sure on the lube and see.

thanks guys for the replies.
 
Do you clean or tumble your brass before you size? When I first started reloading I tumbled after resizing and got marks when full length sizing. Now I clean before I do any kind of sizing. I cleaned my dies and it went away.
 
Yes alway tumble first step. I cleaned the die and lube the necks prior as well. I will maybe check with Lee and see what they say. I have run out of things to ask for Xmas so maybe a high end die is in the cards...

Any recommendations?
 
Can you post a picture?

Are they scratches? If so, the Lee Collet die does not (or at least should not) touch the case until the bottom of the die touches the ram.
