[QUOTE="Brent, post: 26170, member: 99"] My 300 Ultra did the same thing, keep adjusting the die down farther until they all just chamber. Mine was pretty **** tight and camming over some before they chambered fine. Are you using a Redding die too? I just neck size with a type S bushing die now, works fine. My chamber has .005" runout on the neck at the 2 o'clock position so if I try to insert the case in opposite of that it binds and won't but barely close. Not worth fixing in this factory bbl. I had a big scratch on all my cases at the shoulder like you were saying, this scratch was in the same location relative to the point of maximum runout, that's how I found the exact position of the RO... I marked all the case heads on one edge and fired them with this line at the 3 o'clock position to keep track of the MAX RO location, I index them to the same spot from now on so I don't have to FL size them all the time, it works fine, flip one 180 degrees and at this point they won't chamber though. Good luck. PS: Factory chambers SUCK! [img]images/icons/rolleyes.gif[/img] [ 03-30-2003: Message edited by: Brent ] [/QUOTE]
