Another COL. Problem
Quote from Reloader on April 18, 2011, 11:49 pmI read the question on OAL variations. I have the same problem. OAL varies as much as .040. 9mm lead cast bullets, both dillon and Lee dies. As suggested in the previous question answers, I measured the seating stem and 30 bullets together, variation was mostly + .001 with a couple of +.002 and -.001. I checked the shell plate holder and found the 2 screws loose and tightened them. Very little difference. I've had the machine since new 9 years and 75,000 rounds ago.
I measured some 38's and 45' I loaded 2 years ago and the max variation was .005 to.008. Most were within .003.
The brass lenth varies from .738 to .748. How much will this affect the COL.?
I am take your advice on the brass and ordring 500 Starline to see if that helps. They vary up to .005 out of the box.
Any suggestions?
