It might be of some help that Judge Benitez should be ruling on the CA ammo purchasing scheme before too long. Oral arguments were months ago. here are the current documents

"The State’s own data shows that from January to June of 2023, the AFS Check
denied 141 prohibited persons, but it wrongfully rejected 58,087 people. Id. at p. 15
(Table 1.1). In other words, the State’s “background check” system wrongfully rejects
around 410 people for each prohibited person it rightfully denies. That is far from an
acceptable ratio, especially when close to 40% of people denied by the AFS Check do not
successfully purchase ammunition even after six months following the denial. Id. at ¶ 31."
They asked for a summary judgement on Oct 2nd, 2023 and a status conference is due 11/13.
