If you think the neck does not have enough clearance to release the bullet then this is a potentially dangerous situation. The only thing that will solve that is neck turning the case or reaming out the chamber. Not using Lapua cases will also help but that's like the tail wagging the dog, you want to be able to use any brand of case so looking at chamber size is a better solution. What is the diameter of your spent cases at the neck?
It could also be from cases that are too long and need to be trimmed. The mouth of the case gets crimped into the bullet when it goes into battery and cannot release the bullet at normal pressures. Case creep in this calibre is not as severe as other calibres but I take it you are checking the case length of every fired round before reloading it?
Or it could be a mistake in recording the velocity; either by the machine or you. No offence, but I do this sometimes and it can send you down the rabbit hole.
