[QUOTE="Bart B, post: 116266, member: 5302"] I've had your same problem with binding bolts on opening them when the bolt face was quite a bit out of square and fired cases were neck sized, reloaded then oriented against the bolt when they were fired again. The angled surface of the case head when first fired would closely match the same angle of the bolt face. On cases first fired and had the greatest case headspace were the ones that usually made the bolt bind on opening. When I full-length sized the fired cases setting the shoulder back a few thousandths of an inch the bolt binding problem went away. Of course when the bolt face was squared with the chamber axis bolt binding never happened for the most part. Sized or new cases with the same exact headspace will not have same headspace after firing; all cases don't expand and/or stretch exactly the same. The longest ones, when only neck sized, would sometimes cause bolt binding when fired again or twice in the same chamber with squared bolt face. This sometimes happens. [/QUOTE]
