Default 40 S&W, 3rd attempt, put a fork in me I'm done.

After the frustrations I had getting a crimp that would work well in my pistol I ordered a RCBS Taper Crimp die. Bumped the powder charge from 4.0gns of W231 to 4.3 in an attempt too get the slide to lock back consistently on the last shot. Still using a 180gn cast TC bullet with a COA of 1.125. Finally everything came together. I have a load that functions reliably, has less felt recoil that the factory ammo I was using and shoots to point of aim out to 25 yds. Given that my 4.0gn load averaged 795fps from my pistol these are probably just over 800fps. Also with a ME of around 260 there is enough power for a walking the dog sidearm.

Next project, find a good load for those Hornady 155gn XTP bullets that came with my die set. I'm looking at a can of 4756 and just over 8 gns is supposed to push those little bullets in the 1200 fps second range.
