As far as I am concerned, this replication of Wills test for Copper coated variant is considered failed.
I tried to pull a bullet from one of the cases, but a standard bullet puller would not work. It ended up requiring a tensile puller to get the bullet out of the case. It measured 259 ft#'s of force required to get the bullet out of the case. (you can see the chew marks from the gripper on the bullet)
I pulled a sample of 10 other rounds for a base line, with the nearest pull being in the ~85 ft# range.
Effectively, the bullet galvanic welded itself to the casing. Once it equalized the electrical potential via the galvanic corrosion, it stabilized with no further effects noted.
That is irrelevant as there is an extremely high risk of over pressure trying to fire that bullet loose.
All of our copper coated is now range fodder only. with replacement rounds on order. Do not attempt to fire these rounds in this condition.
