What dies are you using now? Does your sizing die have a button that gets dragged through the neck? If so, is it set centrally?
Kev.
I know what you mean about manual alignment. It seems wrong in such a precision game.
But what do you think of this?
When I get a problem like this, I immediately get surfing, and last night after absorbing the advice, I came across an internet article written by a bloke who was having run out problems.
He was told by his mate to turn the bullet as it went into the die. He had tried it and it hadn't worked.
This morning, first thing, I made up another batch. When I seated the bullet, I got it as straight as I could to start with, then ran it into the die a few thou, then lowered it. I turned the bullet 90 degrees, and ran it in another few thou. I kept repeating this until the COAL was at the required figure. I guess I had to do it about 7 times. I then rolled them. Not a visible trace of run out was seen. Straight as a die (well, not mine)
With the original lot, there was a massive wobble when rolled.
Anyway, I did it again this afternoon. Same routine. Again, no visible run out.
The dies I am using are the dies that came with the master supreme kit. I have to say they feel a little basic, particularly the bullet seating die. The depth seating screw feels very 'dry' and grindy if that makes sense, as tho it needs oiling.
What do you reckon?
Makes sense that to move the bullet head round would 'share out' the imperfection in the die. There probably still is run out, but its not all in one area.
