njl Posted October 16, 2009 Share Posted October 16, 2009 I'm loading 9mm on my RL550B using Dillon 9mm dies and lock rings. I keep noticing every couple hundred rounds that my resizing die is loose. Using the Dillon wrench, I've tightened the lock ring about as much as I think I can without breaking something. Is there some other trick I should try? Maybe using 2 lockrings?

Pat Miles Posted October 16, 2009 Share Posted October 16, 2009 I use an all Whitworth, all metric, all SAE left handed adjustable spanner wrench more commonly known as a crescent wrench. I apply a goodly amount of torque and have never had a problem with a loose die on either of my 650's. The stamped steel wrench that came with the machines just didn't work for me. Adios, Pat Link to comment Share on other sites More sharing options...
Sarge Posted October 16, 2009 Share Posted October 16, 2009 Mine came loose after about 3000. I now check it periodically. Link to comment Share on other sites More sharing options...
Pezco Posted October 16, 2009 Share Posted October 16, 2009 You could put the second lock ring on the bottom of the resize die. That is what I do with the Lee U-dies in my Dillon. Link to comment Share on other sites More sharing options...

So you have one lock ring on the top side and one on the bottom side of the tool head? Link to comment Share on other sites More sharing options...
