The Forster Bench Rest Full-Length Die Set, .300 Win Mag (brand part no. 004471) is a two-die combination built for serious .300 Win Mag reloaders who want bolt-action and single-shot rifle brass sized with match-grade precision. The set pairs the Forster Bench Rest full-length sizer with the Forster Bench Rest seating die, and both dies use an elevated expander button that keeps the cartridge case and neck precisely aligned through the entire sizing stroke. That alignment is what separates a Bench Rest-grade die from a generic set, especially when you’re chasing tight groups in .300 Win Mag. It’s designed to be efficient and straightforward on the bench without sacrificing the concentricity competitive shooters depend on.
