[QUOTE="Mikecr, post: 971172, member: 1521"] I don't know the root cause but there are factors(a combination) leading to an increase in static friction(stiction). Don't confuse it with normal increasing of bullet grip over time, as necks continue to springback from expansion of seating. Tell you what; I'll sell you the solution for 1cent/shot & trust you to pay me for application of it :) It's carbon film,, Yep, that hi-tech stuff left in your necks on firing. If you don't wet lube bullets with water soluble case lube and stop cleaning away the magic carbon film, you will never run into the condition considered cold welding. Ever. With the carbon film, your seating forces will be more consistent and with that your seating depths will be more consistent(I should charge 3cents/shot). These folks so proud of squeaky clean case insides, are setting themselves up for cold welding, inconsistent seating forces, and inconsistent seating depths. And for no gain whatsoever. They are funny people.. [/QUOTE]
