Well, finally got off my Butt to do some reloading. Been along time. Now I know why, PITA!
I set up my Dillon 550b to reload some 10mm. I have a set of hornady new dimension dies. I know that I have used them in my Hornady L-N-L press with good results. Now when I went out to find them they were in a Dillon tool head, but Im not sure I got as far as reloading them with it, but probably cause they were set real close, and I kind of seem to remember reloading some 135 grainers (just a few though)
Anyway, I have burnt up about 50 cases trying to figure out why in the heck I cant get a consistant COL for each round. Every round is anywhere between 1.255 and 1.266!
Here is what I have checked
1. Dirt on the shellplate
2. Proper adjustment of the seater die. (including all lock rings tight)
3. Consitant brass and bullet lengths
4. proper seating of primers
5. consistant powder charge
6.cleanliness of the seater die.
7. proper adjustment of all the other dies
9. chamfer case mouths.
One clue is that there is a nasty ring on the nose of the bullet. And it seems that alot of pressure is required to seat the bullet. Im half suspicious that the die is crimping the bullet before it is seated, but it shouldnt be. But if that is the case then its because I cant adjust the die correctly because of its bodies long length and the shortness of the seater adjustment.
ANd no Im not trying to crimp with that seater die. I have a seperate crimp die Im using.
