I am having problems loading 210 VDL for my ultra mag , first I am using a RCBS gold metal die set , I am neck sizing only . .336 most all my cases are max lenght . 2.84- 2.85 max , I use a loaded factory round to adjust my bullet seating die , that is right at 3.60 , . Also I have the chafer tool from RCBS onmy case prep machine the I use to help the VDL as is goes into the neck ,
So my first bullet loaded is 3.609 , then I adjust it down .009 .
Seat the next bullet it's 3.603 . Then I adjust it down .003 .
Seat the next bullet then I get 3.610 ,
It seams the die is all over the place is this something I am doing or not doing ? What die is best to seat VDLs , should I just buy a regular die ? my die is not moving in the press I have it locked down , what could it be ,I am new to reloading , thanks
