I started with 1000, clean, once fired brass from the local range. I sized, deprimed, expanded the neck and started the trimming process with a Forster hand trimmer. I find the neck on most cases still extremely tight on the trimmer pilot. I mean tight-tight, to the point I have to put a huge effort into turning the cutter shaft and sometimes the brass case spins in the collet. I went back to the expander die and checked to make sure I had the case mouth opened enough to start a bullet with my fingers.......it is......so, I don't want to expand the mouth of the case further. After a hundred trims, my fingers get sore enough I take a break. I decided to look at power trimmers for this 9mm project. Because I already had the Forester gear, I figured I'd use the Forster power trimmer and my drill press. I have read the reviews on this trimmer and they all seemed positive. That hasn't been the experience I've had. The trimmer is hard to set up on the drill press, it is difficult if not impossible to set the exact trim length and the pilot still gets stuck in the case mouth and pulls out of the cutter head even though the allen head screw holding it in is as tight as I can get it. And, it is no faster (maybe slower) than using the hand trimmer. It was a total waste of $70 bucks. I'd like to know if there is something I'm missing here. I also reload for 40 S&W and have no trimmer problems. I'm sure its the tapered 9mm case characteristics that have me dreading the second round of reloading for the 9mm. I've now finished 1400 pieces that are ready for powder and bullets. I guess I need another power trimmer. I hate to spend hundreds of dollars just to handle the 9mm's but, I'd rather take a beating than tackle another round with the hand trimmer. I need suggestions from some with more experience on the 9mm. From my experience, the 9mm's stretch a lot after resizing.........much more than the 40's. I've done a similiar amount of 40 S&W and many don't need any trim. All the 9's require trimming. Is trimming 9mm always difficult? Is there some technique I'm missing or do I just need an expensive trimmer?
