Designing the 2-diameter paper patch bullet.

[Distant Thunder]

Just a quick update. I loaded these last night and found I had to set my compression die just a bit deeper, .015", or I had to be way too careful handling the cartridges. The COAL is now 3.470". All else went as planned. I did use my Lee Factory Crimp die to tighten the necks slightly after finger seating the bullets and with the resulting cartridges the bullets stay in place very well. This is SOP anyway, I do this for my Hepburn .45-70, my .45-90 and my .40-65.
