Just an update that is on topic. For the past few days I have seen .17 WSM ammo for sale daily on Cabelas. It is usually sold out anywhere between 10 minutes and 3 hours. Id keep an eye open on it if you still need ammo. I haven't seen ANY 25gr HE ammo for sale at all. I managed to score a single box at Walmart a couple weeks ago but I guess I just got lucky. Anyways below is my ammo source searcher and it works well. You can set it up to play a nice loud sound when it finds something. Just keep it up and running and if you are there and lucky then you can score some ammo lol.
