[QUOTE="MarshMello, post: 2146965, member: 67621"] I agree with the feedback here on a few points. Get the headspace comparator. That will help you see what's changing. Keep doing your homework with the vids and manuals. There is nothing wrong with practicing and sacrificing a few pieces of brass. Just be sure to set those aside as they will tend to fail prematurely as compared to your other brass. Once those get mixed in and you get,say for instance a split neck during a shooting session, you'll be wondering if there is a bigger issue with all of your brass. Most of all, decide on your process. Multiple things could be causing the tight bolt closing. Systematically going through the potential issuess will help you to both confirm and avoid lengthy troubleshooting sessions in the future. I like to start with a factory unfired round. You can pull the firing pin or I just pull bullet/powder/primer and make a dummy round. Measure the shoulder on that as well and log it. If that closes well, go to a piece of 1x fired brass and measure the shoulder on that. Measure the case length to make sure that is in spec. Trim as necessary. Resize to get a .002-.003 bump. Once you establish that you can moving on to other potential causes. [/QUOTE]
