Hello guys, started loading for my .30-06 with Federal once fired brass, trimmed to 2.49". Chamber great until a bullet is seated then this weird ring at the top case appears that goes right around. Noticed the rifle bolt closing a little tight but still fine so I thought the shoulder needed bumped a bit. Didn't help. bullet was seated 3.24", bumped back to 3.195". Factory ammo at 3.27" chambered fine so it wasn't the bullet out to far. Then I made a more compressed load and it would not let the bolt close at all and I noticed this ring. Is my seater set wrong, crimp problem? Dies are RCBS. I am not crimping but thought die is trying too?
