Hello Everyone! I just picked up 1,000 once fired, unprocessed 9mm Speer brass. I'm going to get the tumbler going this weekend to get them all cleaned up. Should I go ahead and buy a case trimmer to be certain they are all the same length. These rounds are just going to be (hopefully) inexpensive practice rounds for my G19 and G26. Thank you very much!
