Russian/Ukranian ammo has not yet been effected, as it is already in the pipeline.
We will need to see what impact any Executive Orders have on stuff that has not yet been offloaded and cleared customs. For the stuff already in the warehouses the impact will be on what happens to the money owed to the Russians/Ukranians, and how much the wholesalers/distributors/vendors decide to raise the price on speculation of future scarcity.
stay safe.
