This sounded familiar so I went back and found this thread.

It sounds like a small base die slightly out of adjustment may be the problem. If not screwed down tightly to meet the shell holder, than a quarter turn added, the base of the brass doesn't get sized.
Read the thread, we have discussed this before. Hopefully by next week I will be reporting on my recent reloads, and hopefully I adjusted it right.
Yes guys, I am using small base dies. And the reloads I was using were loaded 3 yr ago. Nightforce's explanation of the jamming turned on light bulbs. I assume that at least some of the time I didn't adjust the die correctly to resize the brass all the way to the base. Problem is, I probably have 700+ rounds of old reloads and some likely were sized correctly and some probably weren't. That's a dilema.
I think that covers the sizing problem. Now I have to work on the accuracy.
I am going to use nothing but factory loads till I get both issues resolved and then start working through reloads (loaded either 50 or 100 at a time) I guess if a round jams the gun, I will have to take that whole box of rounds apart and do them over. That sucks

Just set them aside for the bolt gun, lots easier to take them apart with the pull of the trigger
probably what I will do. Oh well, I will not be signing in to this forum for the next week. Taking the carbines and the bolt gun to Meunster Tx to chase hogs.

Regarding your jamming issue, are you using a full length die? Make sure you are sizing your brass enough, maybe check it with a case gauge. Regarding the accuracy, have you worked up a specific load for your rifle? I have an AR10 SASS and have shot several 1/2 to 9/16 inch groups (5 shots) once I got the load dialed in. Use the same bullets, same brass, same primers, and prep your brass. The only variation you should have is powder weight. Start with a low powder weight and work up by half grain increments. Shoot 3 shot groups until you get a good group. Once you do that, load up some more rounds using powder just under, just over and equal to the weight you shot the good 3 shot group with. From there, try 5 shot groups. Also, make sure all the copper is out of your barrel. Good luck and happy shooting.

I have only used a full length die myself but had to run some of my cases through several times before they checked out OK in the case gauge. This is the stage I would discover that many had bent rims. A second or third sizing sometimes remedied this and sometimes not.
