Starline has been good in the cartridges I've used it in. It's not Lapua but it's always going to be better than Federal or newer made Winchester and I'd argue its equal to the new crap that Nosler is putting out
I have used Starline brass in .308 Win and I like it best of the "cheap" brass brands. it aint Lapua/Alpha quality brass but for the money its good stuff....Hb
