I just took advantage of the CDNN Steyr blow-out by getting the HS50. I can't wait to take the beast over to a nearby 1000-yd range. Now it is time to think about optics and ammunition. Any recommendations on a scope? It looks like sportsmansguide.com only has spotter ammo available on the website and ammoman.com appears to be sold out. Any other good ammo sources for milsurp ammo? Thanks.
