I recently bought a box of Ultramax 168 HPBT in 308 and have to say this stuff really impressed me. My rifle shot sub 1/2 MOA all day. I payed $15 a box. Anyone else had good luck with this ammo? Im curious does anyone know what type of powder ultramax uses? Im going to handload some with the same overall length and bullet. Just gotta figure out the powder. thanks, boydo
