For tactical purposes, what is a good starting point as far as how much neck length to size using the Redding FULL bushing size die in 6.5x47? No-turn match chamber with a .104" throat, PTG reamer #11724.

Re: Redding FULL Bushing die; How much neck to size?
I don't have one of that particular caliber. But after chasing my tail around handloading for a long time, I just load by full length sizing everything to the very minimum that makes the rifle work. That's usually bumping the shoulder back .002" On my dies that sizes the whole neck.

+1 Victor. I load all calibers with a 2 or 3 thou bump on the shoulder which sizes the entire neck. I believe my 6.5x47 is bumped 3 thou, this is also where my shell plate hits the bottom of the die. It's really convenient not to have to remember where it was from last time, just screw it in till it hits and size.

Re: Redding FULL Bushing die; How much neck to size?
For the last few years I have been using round cut shims from MSC. They have thicknesses from .0015" on up. I think that's a more accurate way to make the adjustment. But everybody has their own way.

Re: Redding FULL Bushing die; How much neck to size?
If i'm wrong please forgive me but I don't think you understand. The Redding FULL bushing die can be set to bump the should, which I do at .0015", AND it can be set to size a varying amount of neck length. I'm just trying to find a good place to start.

Every time I tried partial sizing the neck I always had problems. Mainly the groups fall off. But I'm sure there will be others chiming in and tell you everything about it.

Re: Redding FULL Bushing die; How much neck to size?
I guess a good place to start is all the way down, sizing the entire neck. Your bullet will be touching the entire neck and even be a little below the shoulder/neck junction. More neck is good (from what I hear), use different bushings to get less or more neck tension.
I guess I really don't understand so please explain. Why would you only want to size part of the neck?

Do you mean backing off on the bushing nut so that the bushing doesn't size all the way to the shoulder? I usually back the bushing nut off 1/4 turn and this leaves about .050 or so of unsized neck.

Re: Redding FULL Bushing die; How much neck to size?
Vinconco has it correct. Technically, one can size any amount of the neck, little to all. Just trying to find folks who have played enough with these dies to give an educated/experienced bit of info.

You should back it out just enough to hear it move when you shake it, this will also alow some movement of the bushing for allignment.

I understand how it works and how to set it.

Re: Redding FULL Bushing die; How much neck to size?
I was/am all prepaired to run this experiment, however, I found a load recipie that simply let me size the entire neck. Since I was more thanhappy with the recipie's performance, I saw no need to run the experiment.
I ended up using a full length neck size with 0.002 neck tension.

Leaving the last .050 unsized could align the case a little better in the chamber and mitigate any effects of donut formation.

Re: Redding FULL Bushing die; How much neck to size?
You are not gaining anything by only sizing a portion of the neck b/c the unsized portion of the neck isnt touching the chamber b/c all brass has a natural spring back of about .001in this is why you can easily extract and load a fired peice of brass w/ease. I size to with in about .010in or so of the neck shoulder junction. But if you must only size a portion of your neck find your seating depth and where the bottom of the ogive of the bullet stops that is where to set the bottom of your bushing.
