I talk like I know what I am talking about, but I have yet to seat a bullet.
Been reading like crazy and accumulating tools and materials for weeks now. I am very close to getting going. Awaiting my A&D scale to show up and a few other odds and ends. But I have been following this topic closely (here and in other threads).
My planned workflow is going to include wet tumbling, annealing, full length resizing (via Redding bushing) and neck expansion (Sinclair mandrel). With all of this done after each firing. Especially given the cleaning and annealing steps, I read of this being a potential driver for higher pressure required for bullet seating plus hints of an increasing bond (molecular? electrochemical such as galvanic corrosion?) between bullet and neck wall over time. Which to me means that while care is given to set neck tension, factors beyond pure tension can impact the grip/adhesion level between the bullet and the neck interior. With some advocates not wanting to clean or anneal so that the inside of the neck maintains some level of material (carbon?) left over from prior firings to act as both a lubricant and barrier to prevent bullet to neck bonding.
So at this moment if someone (like me) plans to extensively clean the brass as well as anneal, that some type of lubricant (such as a dry lubricant) inside the neck is a good thing. I see people can measure seating force via what I assume is something like a load cell and arbor press. Has anyone done something like a study of the force to remove a bullet from a case once seated? With time (days, weeks, months) as the variable? if there was a correlation then I can see that velocity may vary depending upon how long the ammo has sat after being loaded? And to go along with this potential, that the use of something like a dry lubricant can maybe help both bullet seating as well as prevent unintended bullet to neck wall bonds from developing?
Thoughts? This may very well be ground previously covered and I am just catching up.
