The 35 is slowly sliding into obscurity, I almost never see ammo on shelves any more and it is usually Hornady. It is a good enough round, but not really better than other similar rounds. I have one, it is a nice gun to be different. But while factory ammo is technically still produced not enough is sold for a steady supply. The factories make a small run once in a while, when it is sold it may be a year before they get around to making more.
I have several boxes put back. No more often than I shoot mine it will last me a while.
