Hello folks, New member here. I have a 308-1 and I've shot several different brands of 308 ammo out of it. Each rifle is picky about the ammo it likes. Mine , in particular, groups amazingly well with Hornady 150 GR SST ammo. It does not group well with any other ammo it seems. I've always been a bit partial to Hornady so I'm glad I have a rifle that eats it up well.
