This brass sure smells and talks like Winchester. I weighed a bunch tonight. All sized and trimmed. 157grs. Falls into the same range as my Winchester brass. Looks the same internally. 308 Win head stamp looks identical to the Win also.
My Federal, Lapua, Rem, PPU and S&B all land around 174. The box says made in USA. I don't think Cabela's would push imported ammo and market it as made in USA. My money is on a Winchester product for brass.
