which neck bushing to get?

[cocopuff]

How do I determin which size neck bushing to get for the 6br?

These are the new Hornady custom dies (neck) thank for any
advice on this..John

Measure a loaded round with your bullet seated, and deduct .002, that is the bushing you need to start with.
Bushings .001 under, and over that number will be useful for fine tuning...

Here is the instructions from Forester Products. It covers their "rules" for accuracy and gives their formulas how to determine the correct die size.

Hope this helps

Get .265/.266/.267 and one of those will be what your looking for.

To everyone that posted under this post , how do you all know what his loaded diameter is ? Curious and wondering ???!! Preacher has the correct answer , just wondering how everyone arrived at their measurements .

I gave this response as to the question of using Redding Dies: "The neck size of the bushing will depend on what your loaded round measures. For example a loaded round of .267 could use a bushing of .266 if you only wanted .001 of tension. If I were you I would get a couple of bushings (.266 and .265 for example) and see what gives the best accuracy. Some bullet power combinations like a lot of tension, some do not. This is what makes it all so much fun." To get to the loaded round size you can use either a dial or digital caliper, or a std. or digital micrometer. I don't know of anyone who uses a bushing equal to the loaded round size as that would basically give no tension. Depending on the OAL that you finally arrive at for best accuracy, if it is at jam or greater there is a possibility of leaving a bullet stuck in the rifling, if you had to unload.

Excellent advice IMHO. Especially the part of having to unload an already chambered, but unfired round. Leaves a real mess to clean out which is why you should also carry a small can of compressed air to help get out those small granuals of powder. Been there a few times myself.
