Nosler 300 Weatherby Magnum Brass (brand part no. 10180) is Factory 1st cartridge brass, meaning it comes straight from Nosler’s production line rather than being reclaimed or reconditioned. This 50-count bag gives 300 Weatherby Magnum handloaders a full batch of fresh, unfired cases to build a load around from the very first firing. Because the brass hasn’t been fired or resized before, reloaders get a consistent baseline for case capacity and neck tension across the entire batch, which matters for a hard-hitting long-range magnum like the 300 Weatherby. It’s a straightforward, dependable option for anyone starting a new 300 Weatherby Magnum load from scratch.
