Was in Bass Pro today and say an end cap display of a new Winchester ammo line. The ammo was SX9, SX40, SX45. Was in a black/red box IIRC and the gist of it was you could get FMJ training ammo or JHP defensive ammo loaded to the same specs if I read the boxes correctly. The ammo was priced about the same as the WWB USA stuff.
The Winchester web site doesn't list this ammo (or I can't find it) and I was wondering if anyone had the skinny on it?
