Thanks. I read all 7 pages of the HEADSPACE sticky and minimum headspace was said to be best if you handload, which I plan on doing soon. I just wanted to make sure it would be safe. I guess I could back it off a little and still be ok, it's not diffucult to do. Also, some once fired .243 and .22-250 brass chambered without problem as it is. I believe the 22-250 has a sloghtly shorter headspace, but the .243 is the same, right?
