Re: Fixing bullet runout?

In order to cure the problem I took several steps. Remove the expander ball from your resizing die. The expander will stretch the case as it pulls through and will almost always cause runout.
Make sure you lube your cases well. I use imperial sizing die wax.

That is by far some of the best advice in this post.
My technique involves using a tight neck chamber. I dont get any neck expansion. All I do is run my cases through a body die and then neck size them. The less brass you compress, the less runout you will have. Scince I only neck size .002" of brass, I dont get any runout. With the tight neck chamber, if you have any run out, you will feel the neck hitting the chamber. Obviously, I dont use an expander ball. The deal here is very complicated, but for me, thats what works.
In part, the same can work for your. Neck size only what you have to after running your cases through a body die without the use of an expanderball.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
