I zeroed my Savage with bullets (Ammo) that would always (hopefully) be readily available at any (hopefully) Wal Mart in the country!
Remington UMC 50gr HP's.
I got that gun as a spare/loaner, and that's how I wanted to feed it, any where, any time, at a moment's notice. I asked specifically and they looked them up for me and told me they were a standard inventory item. They always tried to have them, and every Wal-Mart in the country stocked them.
Now I'm getting another 223 bolt gun, so I might start loading the 223 again. I sure like V-max in my handloads.
