Trying to set up for some more economical food for the Desert Eagle, savings is going to be great if I can get this off the ground, this is my first straight wall magnum cartrige I am attempting to reload, so yet another learning hurtle.
This is the also the first time I have ever had such difficulty in achieving a proper crimp. I am using once fired and resized Hornady brass with Speer 300 TMJ's and seating with a brand new RCBS Seating and TC die. I have seated bullets without crimping, as a second step back the seater plug off and tighten down the die body and crimp. I cannot get a good, reliable crimp on these cartriges, at any adjustment point the bullets very easily setback, simply tap the cartrige on the bench from 1" above the bench surface and setback occurs. Add 1/4 turn on the die and setback stops but the bullets deform and freely turn with your fingertips, add another 1/4 turn and the brass begins to collapse. I am certain there is no sweetspot with the crimp, in addition I tried a Lee seating and TC die, same outcome. The Speer bullets remind me of Berrys plated which responded the same way with any bit too much crimp. Any magnum/50AE loaders out there that may lend any advice?
