Description
The Redding #35 Competition Shellholder Set takes the guesswork out of setting shoulder bump on your large magnum brass. Instead of backing your sizing die in and out and chasing an inconsistent result, you set the die once with a firm cam-over and let the shellholders do the fine tuning. Each one sits a touch taller than a standard holder, so swapping between them changes how far the shoulder gets pushed back without ever disturbing your die setting. That means repeatable headspace every single time you size a case.
How the Redding #35 Set Works
The set includes five shellholders in .002" increments, marked +.002", +.004", +.006", +.008", and +.010". You start with the +.010" holder and size a piece of fired brass, then measure. If the shoulder hasn't moved back where you want it, you step down to the next holder and size again, working your way down until you hit your target bump. Most handloaders aim for around .002" of bump on brass fired in their own rifle, which keeps things chambering smoothly while extending case life. A storage box is included to keep the set organized on the bench, and the lid is a handy spot to jot down which holder works for which rifle.
Calibers the #35 Shellholder Fits
This one is built for the big bore and long-range magnum crowd. It works with 338 Lapua Magnum, 416 Rigby, 300 Lapua Magnum, 300 Pegasus, 300 Baer, 330 Baer, 30/338 Lapua Magnum, and 30/416 Rigby Improved. If you're loading any of those heavy hitters, this is the headspace rhead you've been after.
Why Reloaders Reach for the Redding Competition Set
Each shellholder carries a distinct black oxide finish and is clearly marked so there's no squinting to figure out which is which. The real draw is consistency. Once you've found the right holder for your chamber, your results are repeatable with no further die adjustment needed, which is exactly what you want when you're building precision ammo. These are made in the USA and pair perfectly with standard Redding shellholders and competition dies.

Frequently Asked Questions
How do I use the Redding #35 Competition Shellholder Set to set shoulder bump?
Set your sizing die to make firm contact with a standard shellholder, then swap in the competition holders to fine tune. Start with the +.010" holder, size a piece of fired brass, and measure the shoulder. Step down through the holders in .002" increments until you reach the bump you want, which is usually around .002" for brass fired in your own rifle.
What calibers does the Redding #35 shellholder set fit?
The #35 set covers the large magnum cases, including 338 Lapua Magnum, 416 Rigby, 300 Lapua Magnum, 300 Pegasus, 300 Baer, 330 Baer, 30/338 Lapua Magnum, and 30/416 Rigby Improved. If you're loading one of these big cartridges, this is the correct set. Redding publishes a shellholder-by-cartridge chart if you want to double check your specific round.
Does the Redding Competition Shellholder Set include a standard shellholder?
No, the set contains only the five competition holders in +.002" through +.010" increments. You'll still want a standard Redding shellholder to set up your die initially, since the competition holders are designed to reduce bump from that baseline. Matching a standard Redding holder with this set gives you the most predictable results.
Will this set work with any sizing die?
It works with full-length sizing dies and body dies that are designed to bump the shoulder. Keep in mind a neck-only bushing die does not push the shoulder back, so you'll need a full-length or body die to take advantage of the headspace adjustment. The holders fit single stage and turret presses.
