sounds to me like a resizing problem, do you have your resizing die set correctly? also what brand of brass are you using?? with my 9mm and 45 acp loads I dont even use a crimp the case mouth already has enough tension that I feel it is not necissary to use a crimp. what brand, type and diameter of bullet are you using?? sounds like your case mouth is to large for the bullet diameter but the crimp is grabbing and forming a groove which would allow it to spin but not pull out, then a wrong size bullet diameter would explain why your crimp die doesnt have enough adjustment. By any chance are you using copper plated lead bullets??? I had a similar problem with berrys plated bullets and remington 38 special +P brass.
