Have you checked to see what the actual bullet jump is from your bullet at load length to the touch point in your throat? In most AR chambers I've found that the jump to the lands is more generous than most think (depends on the bullet and profile). If you have a 50 thou jump to the lands, I wouldn't worry about the bullet moving a few thou when chambered .... unlikely that it would change accuracy that much.
If you can load at max mag length and get within 10-15 thou it might make a difference... but I haven't found too many chambers that have a short jump.
I would also pay attention to the number of firings on the brass and make sure you're not getting too much spring back (or the neck tension you expect)
