Here is a quick copy and paste of what the new regulation looks like. It seems we did not have an impact.

NEW SECTION
WAC 232-13-130 Firearms and target practicing. (1)(a) It
is unlawful to discharge tracer or incendiary ammunition on
department lands.
(b) It is unlawful to discharge firearms in those portions
of department lands where or when such discharge is prohibited
by department posted notice or from or within five hundred feet
of a department designated campground. Violating this
subsection is a gross misdemeanor if the violation creates a
substantial risk of death or serious physical injury to another
person, pursuant to RCW 9A.36.050.
(c) It is unlawful to fail to remove expended shell
casings, ammunition packaging, or other related target debris,
excluding clay pigeons, when target practicing on department
lands at the conclusion of the target practice session and prior
to departure from the area. Failure to remove any debris
constitutes littering.
(d) The use of glass, signs, appliances, mattresses, TVs,
furniture, and exploding items as targets in target practicing
is prohibited.
(2) The department may designate locations and times for
target practicing.
