Redding bushing ID numbers facing down?

[Joe R]

Hi Guys,
I was looking at the Redding Bushing Neck Sizing Die instructions and it says "Install the proper neck bushing in the Competition Bushing Neck die, with the bushing ID numbers facing down."

Why would it make a difference? I measured both the ID and OD of the bushing and I can't see any difference, what gives?

i would like to know the answer to this also.

Redding sizes are stamped.....this creates a surface that is not flat, and could cause the bushing to cant since the stamping is on one side. The bushing does its work on the upstroke, therefore the top of the bushing is more critical than the bottom. Remember the bushings are supposed to float.
Wilson etches the size numbers, eliminating any potential problem......and they're a tad less expensive, which adds up when you require a few dozen sizes.

The admonition used to be numbers up but was changed so as to size the neck a bit longer in length. Works better considering how much neck is not sized at all with the Type S dies.

I was told by one Redding Tech, a long time ago, that the instruction for placing the ID numbers facing down adds to the notion of doing something the same way consistently [over and over again] which originates from the idea that accuracy is based on consistency, consistency, and consistency. Hence, no difference in measurements.

This makes sense to me, thank you very much for responding.

Kindest regards,

Does one end have a bevel on it?

I think some do more than others.

I have about a dozen Redding bushings and they're equally beveled on both ends.

You can get a .0005" variation by turning them up or down, on some bushings.
also best to measure for any run out if you have the numbers up.

Wilson bushings are .0005 different in size end to end. That way you can switch the bushing end to end to change your sizing. Don't ask me which end is small or large. I have carbide bushings for my 22, 6mm, 6.5mm, and 30 cal. Mine are beveled on one side only.
