Full length sizer bushings

[msalm]

I've made my own bushings by turning OD and boring ID in one setup out of O1 steel. Harden, temper then back on the lathe to polish with a brass lap held in the tailstock to keep everything straight and even...they work well but I have more time in them than just buying one. It is handy to make any size you want with no wait though.

Yeah if you read a reamer print, most designs show no taper in the neck. Only the body. So neck bushings shouldn't have a taper either.

Exhibit 'A': reamer print on my 300 NMI, .339" Neck

No one is suggesting it puts a taper on your neck. The bushing sizes down the neck to the point of smallest dimension. That happens to be an eight or so from the end of the bushing. So you will theoretically have a slight .0002" larger neck nearer the shoulder than the rest of the neck. Well within your prints .0005" tolerance. Some of the bushing makers even tell you to flip them numbers side down for the tightest sizing up to the shoulder. These things are honed out and polished with mandrels in mass production, stamped with size at the end. They aren't custom made on a lathe to the exact size you need and polished in a straight line.

Ooooooh. You're talking about the bushing chamfer... Not "taper".

They are usually radiused at the large end. I was just trying to help the OP, not argue with how neck bushings are made and used.

 

[Ledd Slinger]

Not trying to argue either. When a person says their bushing is "tapered" people get a different idea in their head. Thought maybe you had faulty bushings when you said they were tapered. No biggie. We know what you're talking about now

Well, Wilson bushings had a .0005 taper on the ID. If you wanted a little smaller diameter you reversed the bushing in the holder.

Get the nitride bushings from Redding. I've never been impressed with the bushings that Whidden supplies.

 

[Riesel]

So, smallest hole side down. That should make the neck consistent from mouth to neck shoulder. If I'm following this thread correctly, that would be number side down.

The hornady’s should work too. They work in the Redding dies.

Thank You for posting this Butch. LE Wilson makes their bushings for the very reason that you quoted. On Le Wilson's instruction page, it states that their bushings are made with a .003 taper.
