Pending tomorrow's finalization hearing, looks like Vista Outdoors pretty much is the ammo market now ... American Eagle, Blazer, Butler Creek, CCI, Estate, Federal, Independence, Speer, and now Remington. Add them together and that's way up there in total percentage what's available at most stores. Only serious competitors will be the importers like Wolf/TulAmmo and house brands sourced from overseas providers.
They'll also supply a big chunk of the reloading, budget optics, and cleaning supplies markets, too.
