How mant thousandth's does one turn of the die equal?

[Bart B.]

Why does one need to get critical with the adjustment of the dies?

Well, no slam's intended, but some folks can shoot their stuff well enough to tell when their sub 1/4 MOA accuracy goes up to 3/8 MOA. And they can get 20 to 30 maximum reloads per case with dies set properly to the Nth degree instead of only 3 or 4.

But everyone doesn't want nor need that level and are happy with what they get. Reload as you choose to meet your own objectives.

Is all this knowledge necessary? Darn, I thought I was doin good...

seating stem

not sure if its been said yet I read through quickly but on my lee dies 1 revolution of the seating stem is 0.0565. For some reason I have this divided into 16ths to .0035. Then I have a spreadsheet that I can type in the desired length and what the actually have. It then tells me to turn 1 rev and take north and turn it to south west. Kind of hard to explain but when switching bullets this is a time saver. I hate making a short bullet and pulling so everytime I set up the seating die I back out the plug and use this.

Ordell, the topic was about the 7/8 14 threads on the body of the die not the seating stem.

Please forgive my ignorance but is .7 percent error really enough error to worry about? If so then I'd better stay away from reloading.

Depends on what you are trying to accomplish.

All the errors add up orthogonally (RMS style) with the largest ones dominating.

Long range shooters weigh powder to often better than 0.1 grain increments.

They often weigh every single charge.

A volumetric measure gets the 'base' of the charge, and then it is trickled up to the desired value.

Shooting at 100 to 200 yards is much more tolerant than shooting at 1,000 yards and out.
