Weird because I am trying to understand what the data is telling me....
I started reloading again about 1-2 years ago. I had reloaded a little with the stepfather when I was younger but that had been a long while before and all knowledge had evaporated.
I initially read through many of the posts on LRH and a few other sites. and settled on the methodology below based on what I had learned. Went out and aquired the equipment and got busy....Mostly successful thus far.
I decided to go to the next level in quality and purchased a Sinclair Concentricity Guage. I had trusted that using the Collet Neck dies by Lee that I would be getting pretty good loads.
-now to recent issue- Upon setting up to load however I found my concentrity to be worse than I would have conceivably thought.
Steps I tend to use most of the time:
I use Lee Universal Decapper to deprime.
Clean Brass. Walnut Media in Tumbler with Flitz.
As Necessary, indicated by the LNL Guage, I use Full Length Forster Die to bump shoulder. (With deprime/neck sizing rod Removed)
I then run the brass through Lee Collet Die.
Trim if necessary. I sometimes go through and Collet Size again at this point.
Prime Brass using the Forster press as I like the consistent depth control and I am not usually in a rush. It actually goes pretty fast.
Load powder and then seat bullets using Forster Bench Rest Seater or Micrometer Seater depending on what I have for that caliber. <just an FYI..i personally like the Forster BR Seater Dies better than the Micrometer dies. I did pick up a Redding Micrometer to see if I like them better than Forster but I may just sell all of my micrometer dies and go with BR Seaters
Double Check everything at every step of the way and go.....
I now have additional step and check
I recently purchased the Sinclair Concentricity guage and I finally decided to load some rounds in 30-06 for a new Browning BAR I acquired(long story).
When I checked concentricity I was way out of whack.
I was getting on average .007 run out or .014 total indicated run out.
I have checked everything and adjusted dies and press etc...
I get tightest or best run out using the Full length Sizing Die completely sizing necks and then utilizing Benchrest Seater I get runout of .0015 and total indicated of .003.
It appears as if my Collet Die is the cause but it is hard to believe because outside neck measurements are on average very good and match close to the Full Length brass prep.
But the end result is telling.
Has anyone experienced similar or have an idea I have not thought of that might be causing the run out?
I have not yet tried any other calibers yet. This was for 30-06. I initially thought that it might point to a need to anneal the brass but I had some new Lapua on the bench and was able to reproduce the same results.
It seems the more I learn about reloading the more equipment that I need and the more I know I dont kjnow
