Description

This is the die set for 300 WSM reloaders who take brass prep seriously and want to squeeze every bit of accuracy out of their ammo. Redding built the Competition Bushing Neck Die Set for people who sort cases by neck wall thickness or neck turn their brass, and who want fine control over neck tension rather than the one-size-fits-all approach of a standard sizer. It's a three-die package that covers neck sizing, occasional body work, and precision bullet seating all in one box.

What Comes in the 300 WSM Competition Bushing Neck Die Set

The set includes a Competition Bushing Neck Sizing Die, a Body Die, and Redding's Competition Bullet Seating Die. The neck sizing die uses interchangeable bushings so you pick the exact amount of neck tension you want, and a precision ground sliding sleeve captures and aligns the case before the bushing ever touches the neck. That alignment is what keeps neck and bullet runout to a minimum. The body die is there for when cases get sticky after several firings; it full length sizes the body and bumps the shoulder back for easy chambering without disturbing the neck.

Micrometer Control on the Bushing Neck Set

Both the bushing neck sizer and the seater wear micrometer tops. The sizer's micrometer lets you dial in how much of the neck gets sized, and the seater is calibrated in .001 inch increments with a zero set feature so you can return to a favorite seating depth anytime. The Competition Seating Die has long been regarded as the standard for straight line seating, with a seating stem ground to match bullet diameter and a floating bullet guide that keeps everything in line.

A Few Things Worth Knowing

Neck sizing bushings and the shellholder are sold separately, so plan on grabbing a bushing or two sized for your brass and bullet combo. This set does not include an expander button, which is by design for folks running uniform or neck turned brass. Pair it with quality brass and a good set of calipers, and you've got a serious precision loading setup for your 300 WSM.

Frequently Asked Questions

Do I need to buy bushings separately for the 300 WSM bushing neck die set?

Yes. Neck sizing bushings are sold separately so you can match the exact neck tension you want for your brass and bullet combination. A good starting point is to measure the outside neck diameter of a loaded round and subtract .001 to .002 inch to allow for brass spring back. Many reloaders keep a couple of bushings on hand since neck wall thickness varies between brass brands.

Does this die set come with a shellholder?

No, the shellholder is sold separately. You'll want a shellholder sized for the 300 WSM case head to run this set on your press. It's an inexpensive add-on that's easy to pick up alongside your bushings.

Why is there no expander button included with this competition set?

The bushing neck die was designed for reloaders who have sorted or neck turned their brass and prefer to set neck tension with the bushing alone. Skipping the expander keeps things simple for uniform brass and can help reduce neck runout. If you'd rather run an expander, Redding offers carbide size button kits separately.

What does the body die in this set do?

The body die full length sizes the case body and bumps the shoulder back without touching the neck. It's meant for cases that have become hard to chamber after several firings and neck sizings. You won't need it every loading cycle, but it's handy to keep brass chambering smoothly over the long haul.
