Description
This is the Redding 6.5mm tapered sizing button, part number 19263, and it's one of those small parts that makes a real difference once you start doing serious case prep. It's a long, gradually tapered steel expander that opens up the inside of the case neck to 6.5mm (.264) diameter. Because the taper is drawn out instead of abrupt, the neck gets worked open in stages rather than all at once, which keeps the drag down as the case is pulled back off the button and treats your brass more gently in the process.
The real strength here is range. This one button covers a window from .22 caliber all the way up to 6.5mm, so it earns its keep when you're forming brass or necking cases up to the 6.5 family. If you've got the dies and want to turn a 6mm or .22 cal parent case into a .264 neck in a single stroke, this is the tool that does it cleanly.
How the Redding 19263 Tapered Button Fits In
It threads onto a standard Redding decapping rod and runs inside full-length and Type S sizing dies. If you're forming necks up rather than just resizing, plenty of handloaders run it in a die with enough inside diameter to expand the neck without the body touching the die, or thread it into a universal decapping die body. Just remember to set your decapping rod so the pin protrudes correctly and the button never bottoms out on the inside of the case head.
Why Reach for the Tapered 6.5mm Size Button
For anyone chasing consistent neck tension and longer brass life, a tapered expander is a smart upgrade over a standard ball. The gentle entry and exit means less friction, less neck stretch, and a more uniform result from case to case. It's a favorite among 6.5 Creedmoor, 6.5×55, 260 Rem and wildcat reloaders who want their formed brass to come out straight and ready to load. Machined in the USA and built to Redding's usual standard, it's a buy-once part that'll outlast a lot of the brass it shapes.

Frequently Asked Questions
What does the Redding 6.5mm tapered sizing button actually do?
It's a long, tapered expander that opens the inside of a case neck out to 6.5mm (.264) diameter. The gradual taper works the neck open in stages, which lowers friction as the case comes off the button and reduces stress on the brass. That makes it handy both for routine resizing and for forming necks up to the 6.5 family.
What cartridges can I form with the 19263 button?
This button covers a range from .22 caliber up to 6.5mm, so it works for necking up parent brass as well as standard neck expansion. It's commonly used by folks loading 6.5 Creedmoor, 6.5×55, 260 Remington and various 6.5 wildcats. If your goal is turning a smaller neck into a .264, this is the part for the job.
How does the tapered button mount in my die?
It threads directly onto a standard Redding decapping rod and runs inside your full-length or Type S sizing die. When you tighten it down, the slotted jaw on the rod closes around the decapping pin to hold everything in place. Set the rod so the pin protrudes about 3/16 inch and the button won't bottom out inside the case head.
Is a tapered button better than a standard expander ball?
For precision work, a lot of handloaders prefer the tapered design because the drawn-out taper means less drag and less neck stretch on the way out. That tends to give more consistent neck tension and can stretch out brass life. If you're chasing uniform results from case to case, it's a worthwhile upgrade.
