I called a number of sporting goods stores in the Sacramento, CA to inquire about a Howa rifle in 7mm Remington Magnum. Most said they did not have the firearm in stock but could order one and have it delivered to their shop within the 10 day waiting period required by California law. I presume many gun shops, particularly small ones, do not keep a large inventory of Howa rifles but could order one for delivery in a reasonable amount of time.
