Redding built the Master Hunter line for the handloader who refuses to choose between field reliability and bench-rest accuracy. This 300 Win Mag set (MH-C) combines a full-length sizing die with their highly respected Competition Seating Die, giving you ammo that chambers smoothly when a fast follow-up shot matters while still holding the kind of concentricity that tightens groups. The idea came out of the success of Redding's National Match dies, reworked for hunters who put rounds through bolt guns in real conditions.
Full-length sizing is the heart of this set. It resizes the entire case and sets the shoulder back as needed, so every round drops into any SAAMI-standard chamber without a fight. The full-length die uses a free-floating carbide size button, which makes inside neck resizing smoother and easier, and you don't have to lube the inside of the neck to get there. For a hard-recoiling magnum like the 300 Win Mag, that dependable chambering is worth a lot when you're working a bolt on a quartering bull elk.
The seating die is where Redding really flexes. It uses an internal sliding sleeve that fully supports and aligns both the case and bullet before seating ever begins, which is how you get that precise bullet-to-neck alignment. The seating stem is ground to match jacketed bullet diameters, and the micrometer top adjusts in .001-inch increments so you can dial seating depth exactly and return to your favorite load every time.
These dies are machined on Super-Precision lathes from quality alloy steel, heat treated, and hand polished for smooth operation. All Redding dies use the industry-standard 7/8-14 thread, so they'll thread right into any common single-stage or turret press. Worth noting up front: the Competition Seating Die isn't meant for compressed loads, and the shell holder is sold separately. For a 300 Win Mag shooter chasing tight, repeatable groups and rock-solid feeding, this is about as good as it gets short of going fully custom.
No, the shell holder is not included and is sold separately. You'll need to match it to your 300 Win Mag case head, which uses the same shell holder as several other belted magnums. Pick one up alongside the set if you don't already have it.
The Master Hunter set upgrades the seating die to Redding's Competition Seating Die, which uses an internal sliding sleeve to align the case and bullet for better concentricity. The full-length sizing die also features a free-floating carbide size button for smoother neck resizing. In short, you're getting match-grade seating precision paired with reliable full-length sizing.
No, the Competition Seating Die does not include a crimp feature. Many premium hunting bullets lack a crimp groove anyway, so a roll crimp often isn't needed. If you want to crimp, Redding offers a separate accessory crimp die for the 300 Win Mag.
Yes, all Redding dies use the industry-standard 7/8-14 thread, so they'll thread into virtually any single-stage or turret press. The micrometer seating die and full-length sizer are a comfortable fit on common 300 Win Mag presses. Just note the Competition Seating Die isn't recommended for compressed loads.
