The 2 big gun shops I checked here have no 25 or 243 WSSM ammo. Will check 2 more, but the prognosis is not good. From the guys I talked to, you might as well be looking for hen's teeth! I think a while back, a guy called the store I frequent just looking for 25 WSSM BRASS so he could reload some. I think that if I was limited to store-bought ammo, I would have the guns rechambered into something I could get ammo for. The 22 WSSM died a quick death, and all the other WSSM calibers seem to be dying too! On the other hand, the 270 WSM is well liked by all I know who have them...
