as for the cases being too long, you need a set of calipers to measure the cases before you load them. your manual should give you the trim length. as one of the other guys said. pull the bullets and dump the powder and measure the case length. if they are over the max length then trim them back to trim length. as far as the crimping or dents on the cases you need to reset the dies. just follow the instructions that came with your dies. did you clean the dies before using them? if they are new dies there could be some grease inside the dies. for the full length die remove the decapping pin and use the tip end of a cleaning rod and the slotted tip and a patch dipped in hopes #9 and run it up inside the die to remove any oil or grease from inside the die. also look for a small hole located near the top of the threads . use a paperclip or needle to clean this hole out. its important that this hole is kept open.
