You have probably read some comments from me on my liking the Hornady powder measure and I'll try to explain why. A while back I purchased a 550B Dillon along with several die holders and several caliber conversions that were missing the Dillon powder funnels. Looking around the garage I started thinking can I make these work with the older standard die sets and it was quite simple. Die setup would be as follows.. a FL decapping die/sizing die followed by a belling die followed by the Hornady powder measure followed by the bullet seating/ crimp die. Using this setup I now could load 38's and 357's using the Dillon caliber conversion that was missing the powder dropping/belling die. Before I had been loading this caliber using my Lyman-T-Mag press and taking all day to do what I did in a few hours on the 550. The Hornady powder measure works quite well and is so easy to adjust and maintain the correct charge. It also meters difficult powder that my Dillon powder measures have trouble with.
