Description
If you handload the 243 Winchester and chase tight groups, the Redding Competition Seater Die is the kind of tool that quietly makes everything downstream better. The whole design is built around one goal: getting the bullet seated dead straight. A spring-loaded sliding sleeve catches your case and bullet and fully aligns them inside a close-fitting, precision ground chamber before the seating stem ever touches the bullet. That means less runout, better concentricity, and ammo that shoots to the same spot instead of wandering.
How the Redding 243 Winchester Seater Die Dials In Your Depth
Up top you get a micrometer head calibrated in .001 inch increments, and it adjusts infinitely with no clicks to fight through. Dial in exactly where you want your bullet, and when you find the seating depth your rifle loves, the zero set feature lets you re-zero the micrometer to that number so you can return to it any time. The seating stem itself is precision ground to match bullet diameter so closely that Redding says it will float on a column of air, which keeps the nose supported and centered as it goes in.
What the 243 Winchester Competition Seating Die Does Not Do
This is a dedicated seating die, not a crimp die. It will not crimp the bullet, so if your load calls for a roll or taper crimp you will want to add a separate crimp die to the bench. It is also not recommended for compressed loads. One more thing worth knowing: the shellholder is sold separately, so grab the right one for the 243 case head if you don't already have it.
Made in the USA and machined with the kind of tolerances Redding built its name on, this die drops right into a standard 7/8-14 press. For precision reloaders loading for varmint rifles, target work, or just tack-driving range ammo, it's about as refined as seating gets.

Frequently Asked Questions
Does the Redding 243 Winchester Competition Seater Die crimp the bullet?
No. This is a dedicated seating die and will not crimp the case mouth. If your load needs a crimp, you'll want to add a separate crimp die such as a profile crimp or taper crimp die to your setup.
Do I need a shellholder with this seater die?
Yes, and the shellholder is sold separately. Pick up the correct shellholder sized for the 243 Winchester case head if you don't already have one on the bench.
How precise is the micrometer on this 243 Winchester seater die?
The micrometer head is calibrated in .001 inch increments and adjusts smoothly with no clicks, so you can fine-tune seating depth very precisely. It also has a zero set feature that lets you re-zero the micrometer to your favorite seating depth so you can return to that setting whenever you want.
Is the Redding Competition Seater Die good for compressed loads?
It is not recommended for compressed loads. The sliding sleeve and floating stem design is built for straight-line seating and precision, which makes it a great fit for standard target, varmint, and precision rifle loads in 243 Winchester.
