neck diameter ? - 05/27/16
Recently, I found that the Redding full length sizer (not a bushing die) I have been using creates very little bullet grip.
Winchester brass measures .332-.333 after sizing, loaded rounds measure maybe .0005 more.
I am using a .307 carbide expander ball which does not even touch the inside of the neck when sizing. I can hand seat boat tail bullets by firmly pushing.
I called Redding and asked if a neck diameter of .333 was "in spec" for their dies and wasn't really given a straight answer but was told "it should be fine."
It does not seem fine, and I would be interested in knowing what others find their neck diameter to be after full length resizing in a standard die.
The brass is once fired Winchester brass, neck diameter after firing is .338-.339. I am not turning the necks.
Thank you.
