I just finished loading some .45 ACP and about ten percent of the cases dented at the base of the bullet. This was mixed brass that I picked up cheap from a range. All of it was resized and expanded at the same time in the same way. When I pulled the ram handle I could tell which ones were going to come out duds because there was some sticking and then the sudden release -- no doubt at the point the case gave. The good ones went into the die as smooth as butter, requiring no extra force and exhibiting no crunchy jerk. (Bullets were 230 gr. FMJ, seated at 1.250" and crimped at about .470".) This was the first time I loaded for this caliber and haven't had similar problems since I was overlubing .45-70 prior to resizing. What might I have been doing wrong? Besides buying somebody else's trash.
