I've read that the case can stretch above the head unless a false shoulder is formed, or the bullet jammed Into the lands. Hi Blackaj, Before I started fire forming the cases for the 250 Sav AI I asked Sierra what the best way of going about this is. They use the 250 AI to test their 25 cal projectiles on a daily basis.
