FAQs

Redding Reloading was founded in Virgil, NY in 1946. In 1949, it was moved to a new facility in Cortland, NY where it was incorporated as Redding-Hunter, Inc.

No, there has never been an affiliation between the two companies. RCBS was founded in 1943 by dedicated shooter Fred T. Huntington in Oroville, California whereas Redding Reloading Equipment had its beginnings in Central New York in 1946.

No, Redding products are sold worldwide through a network of over 1,000 valued dealers.

Redding offers a number of different kit options for people looking to get into reloading. Several of our kits are built around the very popular Boss and Boss II Presses. Other kits enable the handloader to purchase everything required but a reloading press and add the press of choice as a separate item. Please click the following link to explore Redding’s different Pro-Paks, Versa Pak and Versa Pak Pro.

All Redding Reloading Equipment is fully warranted to be free from defects in materials and workmanship for life. If you are experiencing an issue, please contact our technical service team via telephone or email.

While slight variations in chamber dimensions exist between these two versions of the 6mm BR, Redding Dies currently marked “6mm BR Norma” are appropriate for both.  Variations in rifling twist rate, throat length, and lead angle do not affect die function or performance.  

Small Base Dies

Benchrest chambers are often intentionally made “tight” at the base for better case-to-chamber fit.  In some cases, it is necessary to use a Small Base Resizing Die so that the case is resized sufficiently to chamber freely.  

Tight Neck Chambers

Chambers with a “tight neck” often require case neck turning / case neck reaming to reduce case neck thickness.  It is important to make sure that there is clearance between the neck of the loaded round and the neck area of the chamber so that the case neck can expand and safely release the bullet when fired.  Any trouble in chambering is a caution flag!  If possible, compare the neck diameter measurement of a fired case from your chamber with those of a loaded round.  The neck diameter of the fired case should be a minimum of .003” larger than the unfired one.  If in doubt, consult a competent gunsmith.  

Type-S Dies and Competition Bushing Neck Dies

It is sometimes necessary to turn / ream case necks such that a conventional FL or NK Die will not resize the case neck enough to provide adequate neck tension.  If more case neck resizing is needed or desired, a Type-S Bushing Style Die or Competition Bushing Neck Die using Neck Sizing Bushings can be used to accommodate this brass and provide the desired neck tension.

It is recommended to clean your dies with bore solvent and a brass or nylon bore brush. Remove any remaining solvent with a few clean patches and apply a light coat of case lubricant with a q-tip when finished.

NOTE: Some bore solvents have specific guidelines for how long the product should remain in a barrel or bore. See the manufacturer’s instructions and follow their recommendations so that the die(s) are not damaged.

Dies should be coated with a rust preventative before storage and kept in a climate controlled environment.

See Tech Tips Section in the Redding Website.

No – Body Dies were not designed to resize loaded cartridges.

No – the excess pressure will cause damage to the seating stem and internal sliding sleeve.

This damage usually happens when the user adjusts it incorrectly. If the Decapping Rod Assembly is adjusted so that the expander button hits the head of a case during the sizing operation, (adjusted too low) the Decapping Rod will bend or break.

The Decapping Rod Assembly should be adjusted so that the decapping pin protrudes from the bottom of the Die approximately 3/16 of an inch (about the thickness of two Nickels).

While not covered under Warranty, Redding Reloading will happily replace one (1) Decapping Rod for a customer who damages theirs. Subsequent Decapping Rod Assemblies can be purchased from a Redding Dealer or from us directly.

Note: this does not apply to the Competition Neck Sizing Die. Competition Neck Sizing Dies must be sent to Redding Reloading for any repair work.

Redding has the largest library of Custom Dies in the industry. Please visit the Die Finder section of this website. If we do not have your cartridge on record, we may be able to quote it for you on a custom basis. Note: the quotation process often requires sending us a copy of your chamber reamer drawing and/or 5 fired cases from the firearm for examination.

1. Due to the thickness in material, the new Z-Series Dies from Redding are considerably stronger than traditional 7/8” dies. This additional strength reduces deflection during the case resizing operation.
2. Redding’s testing has shown the increased strength of 1” Dies greatly reduces sizing effort.
3. The stronger Z Series Dies produce more uniform resized case dimensions. Every component of accuracy requires better uniformity

The new Redding Z Series Dies fit the majority of the popular single stage presses that are available on the market today.

Simply replacing the existing 7/8”-14 thread adapter with a 1”-14 thread adapter will allow you press to accept the new Z Series Dies (Redding Part # 70030).

If your bench is currently equipped with the legendary T-7 Turret Press, Redding is now offering (2) new turrets that will accept the Z Series Dies.

Part # 67070 is equipped with (7) tapped holes with 1”-14 threads

Part # 67034 features (3) tapped holes with 1”-14 threads and (4) tapped holes with 7/8”-14 threads for maximum flexibility.

Redding’s Ultramag Press is a very large Single Stage press with a huge frame opening of 4 ¾”. Its unique long link compound leverage system has more mechanical advantage over a greater distance than any other press on the market.

Redding also offers the legendary T-7 Turret Reloading press. With a (7) station turret and the flexibility to quickly change turrets to accept the new Z-Series Dies, many of our customers say “this is the best turret press ever.”

The Big Boss II features the Redding’s unique“ Spent Primer Collection System” that is also used on the T-7 and Ultramag presses.

Part # 67070 is equipped with (7) tapped holes, 1”-14 thread.

Part # 67034 features (3) tapped holes 1”-14 thread and (4) tapped holes 7/8”-14 for maximum flexibility.

NO. Forsafety reasons, Redding powder measures should NOT be used for black powder.

The “Instant Indicator can perform multiple tasks including:

• Check uniformity of shoulder bump
• Compare shoulder position of sized cases to fired cases
• Check bullet seating depth uniformity
• Sort cases fired in two or more rifles
• Sort sized cases for uniformity
• Setup sizing die correctly
• Check trim length uniformity
• Sort bullets for uniformity

In most instances, the Instant Indicator may be used to compare headspace (shoulder position) on a “family” of cartridges of different caliber that share the same shoulder angle / body dimensions. For instance, the 243 Winchester, 260 Remington, 7mm-08 Remington, and 308 Winchester are identical dimensionally (excepting the neck/bullet diameter). As such, an instant indicator for any of the cartridges above can be utilized for comparing shoulder positions for this “family”.

Likewise, when the correct Bore Diameter Bushing is used, the same tool may be used for comparing bullet seating depth.

The Model 25 was discontinued from the Redding’s Production Product Line over 20 years ago. Although the press is still active on many reloading benches today, parts availability is extremely limited. Please call Redding at 607-753-3331 and ask for Technical Service.

Both the Model 16 and Model 32 were discontinued from the Redding’s Production Product Line many years ago. Although the presses are still active on reloading benches today, parts availability is extremely limited. Please call Redding at 607-753-3331 and ask for Technical Service.
