Here is a synopsis of the issues with the .45ACP debacle.:
Jim Watson was dead-on: I did not seat too deep. As a matter of fact I seated too shallow as there is ~ 1mm of parallel shaft of bullet projecting out of the mouth of the casing before the taper begins. Therein lies the problem. I pushed the bullet into the crimp and there was still some play in the press which pushed the case a little too far which caused the case to buckle at the base of the bullet (at mid-case). Still with me? Where I went wrong is I assumed the seater die was set correctly. It was not as in the interim from my last re-load of Hornady XTPs I had seated some round nose FMJs. Assumption is the Mother of all disasters. I have a press mount bullet puller that will not grasp the bullet taper sufficiently tight to enable extraction. I will procure a Lee Carbide Factory Crimp Die and run a few rounds thru it to see if it works and will report back to you. Hopefully I can salvage the 200 rounds (9#14oz) of cartridges.
Thanks again for all the help.
