If you are using a standard .308 die and sizing to .308 headspace, you could be working your brass too hard. Firing in a 7.62 NATO chamber can stretch your brass. It may only be a few thou, but it can make a big difference in a short time. Try setting the shoulder back a little less. RCBS lube 2 seems to work better for me than any of the others. Are you lubing the interior of the neck? Are you removing all the lube before seating your projectiles? Also, scrub the heck out of your chamber.
After 50 plus years of reloading, I have had my share of case separations.
There is plenty of excellent new brass available. Skip the once fired crap and you will be well on the way to a more enjoyable experience.
