Guys,
I've got a Forster press and just set up a new Mec press. I've measured the case neck thickness and case runout with Sinclair thickness, and runout gauges. The case neck thickness varies from .005-.0015, and the case runout is .000-.002". I also use an expander mandrel prior to seating during the test just to make sure variences were pushed to the outside. Yet still get from .002-.0045" of bullet runout! I've emailed back and forth with a Redding customer service guy who suggested I get a VLD stem, which I did after our first correspondence. When that didn't fix it, he suggested turning the bullet half way during the seating, making sure the necks are deburred, etc. I've employed that technique for years. And still, the concentricity issues remain. I'm currently using Hornady brass which mentioned above, I've checked and sorted. While not Lapua, i've had good luck in the past and this batch of 6/5 has been quite good! In his last email after I've tried all his known tricks which I already do, he recommended I use Lapua brass. That's when I asked him if he thought I should switch die manufactures too! He's yet to get back to me on that one..
So have you guys had this issue with Redding and how did/do you address and fix it? I think i've tried everything except buying another die which, I'm not wanting to.
