[QUOTE="jd5521, post: 1653725, member: 94694"] You’ve essentially answered your own question. Neck tension changes over time with loaded ammunition. As it changes the Bellar and the neck squeeze whatever is in between them more and more creating a tightening affect we attribute to “cold welding” or “bullet welding”. This even happens if the inside of the necks are clean, albeit it takes longer, because you have two metals squeezing against my ne another. Most shooting within 500 little would be noticed. But passed 500 it can be and more noticeably at 1000 or more. For hunting situations I find (or know) my load prior season. Then right before a season starts I will load and go. That’s why you have a lot of people ask all the time why their first 3-4 shots will be under moa and then a 4-6 shot will be a flier. It’s not the barrel heating up all the time like most people think. It’s 9 times out 10 people shooting older ammunition that has been sitting a while or have factory ammo from a store that’s been sitting in a shelf for long time. [/QUOTE]
