Bushing Die Guys please read

one can always turn the bushing over and use it that way ( up-side down ) can make a difference !!!!! good luck

I'm ok with FL does like the type-s. Basically they size the top 80% of the neck. The bottom 20% gets some sitting by the die, but minimal.

If you want the whole neck sized, SAC makes a neck shoulder bushing die or the Forster system works well. It is just slightly less flexible.

Bingo!

Redding makes a micrometer adjustable, Competition S type bushing neck sizing die. IIRC, it can be set to size the neck to the shoulder.

I have RCBS and Redding Bushings. The ID is constant in the Bushing so what does turning them upside down do?

One side of the bushing has a chamfered edge to help guide the case mouth into the bushing. The other side is squared off more and thus, will size slightly further down the neck.

I only have a few bushing dies all Redding. Mine size the entire neck.

To the OP, not certain what cartridge your loading, but for cases prone to the dreaded doughnut, that unsized portion can hide the effects of its formation for a bit.

Or, for about $20 extra you can tell Forster what neck diameter you want on a f/l sizer. I find this very helpful when I need to play with neck tension, since full length dies (non-bushing) should size the entire neck.

We must have different brand bushings. I just put both my RCBS and Redding Bushings under a magnifying glass and both ends are exactly the same. Both ends have a very slight chamfer. Doesn't really matter which end is up. I was told a long time ago when I first started using bushing that always look at the bushing and keep the letters facing up. (RCBS is on one end and Redding is on the side). Not because there was any difference, but to keep everything in your reloading process consistent. Do everything the same way all the time.

I've read the opposite. Letters down. The supposed reason is that the stamp for the label can have slightly proud edges, and thus that surface won't be quite true, and could induce some tilt in the bushing when it stops against the top of the die.

Seems a bit of a stretch to me, but I do it anyway cause I'm OCD with reloading...

When using bushing die Redding says: Have found that lubricating case necks and installing the bushing numbers down may improve results. Many experienced reloaders like to adjust the die to size 1/2 to 3/4 of the case neck. This has been shown to improve accuracy in most instances. Also hope you all are sorting case neck wall thickness for uniformity , if not don't do the bushing thing- same brass is not always the same !!!!!!! always check and double check .

So, I rush ordered two different bushings and tried to today. They size the diameter of the neck to an appropriate dimension, but I'm concerned that they don't some the whole neck. Is this normal? I've adjusted the die all the way down to the shell holder, and it only sits about .190" of the neck.

Please see photo. I used a sharpie to.color the necks and stroked it in and out of the doe until it wore off to show how much of the neck is being touched by the die. The other piece of Brass is in the picture strictly for reference.

Please comment on whether thos looks normal.tpmyou guys that use these bushing dies regularly.

If you do not resize the entire neck you will eventually form a donut inside the case of the neck. Would recommend changing to a bushing die that allows you to resize the entire neck or change to a standard die that allows you to resize the full length of the neck then order a mandrel to open the neck to your desired neck tension.

Incorrect. In fact it is more common to only size about 3/4 of the neck to allow the donut a place to live. a mandrel will help to push any inconsistencies to the outside of the neck which in theory prevents it from affecting neck tension.
