[QUOTE="swampratt, post: 3587418, member: 15054"] I have had rounds that were harder to close the bolt on. It was not the bullet seating depth it was the fact that during resizing process the shoulders were being set back .002" Which was perfect for me and no issues with stiff bolt closure. What I discovered is if I had neck lube inside a case neck the shoulders all got set back .002" with where I had my die adjusted. If I ran a batch and only lubed a few of the cases inside the neck thinking the expander mandrel had enough lube on it I would be rewarded with neck Ogives all over the place, some .002"-.003" longer than a fired case. I got stiff bolt closure on those. I reloaded at the range a few times and my dies were in the sunshine on a hotish day and I could not set the shoulders back There was just enough expansion from the heated dies to cause this. No matter where I adjusted them. That was an eye opener. [/QUOTE]
