I measured the fired case necks where the bullet does not fit and they are .265", the same as my reloaded rounds with a bullet inserted.
I then thought to measure the case necks where the bullets do fit and they are .270" to .272".
The fact that some of the necks are .272" mean BHW made the barrel correctly.
I think what is happening is with starting loads the brass must be springing back to the resized dimension.
Maybe the case necks should be annealed.
These are all O.D. dimensions.
