Redding Premium Series Full Length 2-Die Set .300 Win
The Redding Premium Series Full Length 2-Die Set for .300 Win Mag gives long-range rifle reloaders the precision upgrades they've been asking for without paying for a three-die setup. This two-die set pairs a full length sizing die with a carbide size button and a seating die equipped with Redding's Bullet Seating Micrometer—the kind of refinement that pays dividends when you're chasing tight groups at distance. If you load .300 Win ammo regularly and want repeatable, consistent results without fiddling with loose seating adjustments, this is the logical step up from standard Series A dies.
The carbide size button in the full length die resizes fired cases smoothly and efficiently, reducing setup wear and handling time between batches. Carbide construction means less lubrication hassle compared to steel buttons, so you spend less time prepping cases and more time at the bench. The Bullet Seating Micrometer on the seating die lets you dial in bullet depth with precision rather than guessing at feel—critical when you're building match-grade or long-range hunting loads where seating depth affects velocity and accuracy.
Redding's Premium Series represents the sweet spot for handloaders who've outgrown entry-level dies but don't need the complexity or cost of a full Deluxe three-die set. You get the two dies that handle the lion's share of the work: sizing and seating. If you later decide you want a dedicated neck-sizing die for even finer control, Redding sells that separately. For .300 Win shooters building quality ammo on a realistic budget, this set delivers measurable improvements in consistency and ease of use.

Frequently Asked Questions
What's included in the Redding Premium Series Full Length 2-Die Set for .300 Win?
The set includes a full length sizing die with a carbide size button and a bullet seating die with a Bullet Seating Micrometer. It does not include a neck sizing die; that is sold separately as part of the Premium Deluxe three-die set.
Can I upgrade to a three-die set later, or do I need to buy a complete new set?
Redding offers the Premium Series in both two-die and three-die (Deluxe) configurations. If you own the two-die set and later want neck sizing capability, you can source a Series A neck sizing die separately, though you should verify compatibility with your reloading press.
What's the advantage of the carbide size button?
Carbide is harder and more wear-resistant than steel. It requires less lubrication, speeds up case resizing, and reduces maintenance over time—especially valuable if you reload high volumes of .300 Win ammo.
How precise is the Bullet Seating Micrometer?
The Bullet Seating Micrometer allows you to dial in bullet seating depth with fine control, eliminating the guesswork of feel-based adjustments. This consistency is crucial for long-range accuracy and handload quality, though we don't have exact measurement increments in our specs—check Redding's full documentation for precision details.
