I live just outside the same town { Polson, Mt. } where Rim Rock Bullets is located on the south end of Flathead Lake. They have a walk in store and sell reloading supply's as well as used guns, and of course their bullets . I have never walked into the store and not been able to get what I was looking for in the way of bullets . Frank Sr., and Frankie are usually busy in some fashion with the business, but always have time to talk to a walk in customer. I lived in Arizona for 34 years, and mail ordered from them for many years. When I moved to western Montana 5+ years ago, getting bullets is now much quicker and easier . I like their bullets, their prices, the convenience and family type atmosphere and will continue to be a loyal customer and friend...good people !
Be patient, they are, and have been swamped, like everyone else.
PS : Heading down there today for .45 and .41 bullets , lol !
